BES Milestones

 

 
 
Dear RHIC Spokespersons:
 
I am writing again to update my request for the beam use requests for the coming RHIC runs.
 
In consultation with the Office of Nuclear Physics we have decided to make a change to the future RHIC run schedule. Specifically, we now plan to run RHIC in both FY16 and FY17, followed by one year (FY18) without a RHIC run during which the low energy RHIC electron cooling (LEReC) system will be installed. The high statistics Beam Energy Scan II is then planned for the years FY19 and FY20. The modified plan will allow for a less aggressive schedule of the LEReC project. It will also relax the conflict between the heavy ion and spin physics programs of RHIC that remained unresolved at last year’s PAC meeting.
 
I request that you submit the annual beam use requests by May 19, 2015. The BURs should be for a 22-week RHIC run in FY16, and either a 15-week or a 22-week RHIC run in FY17.
 
I also ask the STAR Collaboration to present the iTPC proposal to the PAC and to provide an update on experimental efforts aimed at exploring possible phenomenological manifestations of the chiral magnetic effect.
 
Both collaborations should present a tentative schedule for the release of results from the data taken in runs 13 and 14 (p+p, Au+Au 15, Au+Au 200, 3He+Au).
 
Thanks, Berndt

Subject: performance milestones
 
Dear RHIC Collaboration spokespersons & Frithjof:
 
I received a "heads up" from Jim Sowinski that a main scientific performance milestone for nuclear physics in FY15 will be the completion of the analysis of the 15 GeV Au+Au data from Run 14 and the connection of the BES data with lattice QCD calculations. Here is the statement in more detail (Jim's words in blue):
 
“FY15:  Measure bulk properties, particle spectra, correlations and fluctuations in gold + gold collisions at Relativistic Heavy Ion Collider (RHIC) to search for evidence of a critical point in the Quantum Chromodynamics (QCD) matter phase diagram.”
 
We recognize that significant progress has been made in finalizing and collecting the results from Beam Energy Scan I to make the case for BES II.   In evaluating this goal we will primarily be looking at producing results from the 15 GeV run carried out last year.   Other efforts that might contribute towards this measure could be results from the fixed target data taken last year and theoretical efforts such as progress towards better connecting measurements to QGP properties or extending LQCD calculations toward finite chemical potential.
 
It will be important to have tangible results to point to by the end of September 2015. To me this looks eminently doable and desirable in view of the Quark Matter 2015 conference in Kobe.
 
Let me know if you have any questions.

2001 original bylaws

Revised Sections II and III 28 November 2001

 

I. Collaboration Membership

  1. Members

    Scientists, graduate students, engineers and other technically-oriented persons intending to make a significant contribution to this collaboration over a period of a least one year are eligible to be members. Members of other RHIC collaborations will not be members of this collaboration without permission from the Council.

     

  2. Institutions

    Institutions (universities or laboratories) are admitted to the Collaboration by the Council upon recommendation of the Spokesperson. Normally an institution will have at least two Ph.D.s who are eligible to be members. Each institution is responsible for its list of members and for designating a contact person who will receive and disseminate collaboration information within that institution.

     

II. Council

  1. Membership

    The Council will consist of one member from each collaborating institution who will represent the membership from that institution. Institutions are admitted to the Collaboration by the Council upon recommendation of the Spokesperson and upon receiving an affirmative vote of at least 75% of the Council. Each institution will select its representative. Institutions may also be admitted to the Collaboration without Council membership. Such an institution should be affiliated with another institution which has Council membership and may be given its own Council membership at a later time by a vote of the Council. The Spokesperson and Deputy Spokespersons will be ex-officio members of the Council. The Council may add extra members.

    Younger members of the collaboration will be represented by up to three at-large Council members with no more than five years experience beyond the Ph.D., at least one of whom should be a graduate student. Candidates for at-large positions can be either self-nominated or nominated by others after a call for nominations by the Spokesperson. The at-large representatives will be elected by those members of the collaboration with no more than five years experience beyond the Ph.D. Elections should take place at least every two years.

     

  2. Function

    The Council will deal with general issues which concern the collaboration. Examples include the organization and governance of the Collaboration, adoption of the bylaws and amendments thereto, the policy on admission of new members and institutions to the Collaboration, and publication policy. In addition, the Council is responsible for election of the Spokesperson and for approval of Deputy Spokesperson appointments.

     

  3. Governance and Meetings

    The chairperson of the Council is elected by majority vote of the Council from among its ranks. The term of office is two years, and is not renewable. At the end of the Chairperson's first year in office, a deputy is elected who will become the chairperson's successor. After the end of the chairperson's term of office, the chairperson will serve yet another year as deputy.

    Normally, Council meetings will be held during collaboration meetings. At the discretion of the Council Chair, additional meetings can be called with at least two weeks notice. Any Council member unable to attend a given meeting can name a substitute representing the same institution or group. All Council meetings will include a closed session, without the Spokesperson and Deputy Spokesperson(s) present. Elections by the Council, of the Spokesperson or Council Chair or Deputy Chair, must be announced publicly to the entire collaboration at least two weeks in advance of the meeting at which the elections will take place.

     

  4. Voting

    The Council will make decisions on all issues except elections and admission of new institutions based on a simple majority of all voting members. Any member may call for a secret ballot. Votes on adding extra members, admitting new institutions, or amending these bylaws must be announced ahead of time. Proxies to the Council chairperson are allowed for non-election votes, as are electronic meetings and ballots.

    Voting for Spokesperson will be carried out by secret ballot, and without proxies, at publicly announced Council meetings. A quorum of 60% of Council members must be represented at the meeting for a valid vote. A candidate for Spokesperson can be elected in the first round of voting only if he or she receives more than 50% of all votes cast, including abstentions. If no candidate obtains this absolute majority, runoff rounds will be conducted for the top vote-getters until one candidate obtains more than 50% of the votes cast, not counting abstentions. The re-election of a sitting Spokesperson requires a 2/3 majority of the voting representatives present at the meeting.

    Candidates for Spokesperson can be nominated by any member of the collaboration. An ad hoc nomination committee consisting of the Council Chair and two Council members appointed by the Chair will solicit nominations at least 30 days before the election, and will prepare and oversee the ballots.

     

III. Spokesperson

  1. Selection

    The Spokesperson is elected by the Council and serves at its discretion. The normal term of office is 3 years, renewable with a 2/3 majority of the voting Council representatives present at the meeting.

    The Council can decide to terminate the Spokesperson's term in office at any time and to request new elections. Such a termination requires a 3/4 vote of the representatives present at a Council meeting with a quorum of at least 2/3 of the members represented.

     

  2. Function of the Spokesperson

    The Spokesperson will be the representative of the Collaboration in scientific, technical, and managerial concerns. The Spokesperson will be concerned not only with the design and construction of the detector and its upgrades, but also with all other preparations required to operate the experiment efficiently and to publish results in a timely and responsible fashion, and with continued leadership of the Collaboration.

     

  3. Deputy Spokespersons

    There will be up to two deputy spokespersons. The spokesperson and the deputies must all belong to different institutions. The deputy spokespersons will be appointed by the Spokesperson subject to the approval of the Council. The deputy spokespersons provide support and assistance to the Spokesperson in the management of the experiment and collaboration. They may be appointed by the Spokesperson to act on his or her behalf and to represent the Collaboration.

     

IV. Adoption

These bylaws were adopted by the Council on 21 June 1991 and amended on 16 Nov. 1991, 21 April 1993, 7 Nov. 1995, and 28 Nov. 2001.

Charter

August 14, 1994

Goals. The publication goals of the STAR Collaboration are as follows:

  1. The speedy publication of results that the Collaboration has agreed are sound and ready for publication. Here "publication" means the announcement of results through seminars, conferences, and/or scientific journals.
  2. The avoidance of rumors and premature publication. 
  3. The equitable assignment of credit to individuals for their work.

     

Policies.

The following policies and practices have been adopted to further the above listed goals:

 

  1. Data from all parts of the STAR detector shall be available to all members of the STAR Collaboration for analysis. Furthermore, it is the responsibility of all collaborators to see that the necessary correction algorithms and correction parameters be updated and made available to the entire Collaboration in a timely manner. Any member of the Collaboration is free to analyze any part of the data.
  2. Given the overriding principle of open communication within the collaboration, collaborators should, upon request of a colleague, provide relevant code and input assumptions that would permit results to be checked and confirmed.
     
  3. Members of the Collaboration should exercise caution and good judgment when discussing experimental results with individuals outside the Collaboration before the results have been published (i.e., presented publicly in a seminar or conference or submitted for publication in a scientific journal). These results should clearly be labeled "Preliminary". When individuals outside the Collaboration are consulted for advice on the analysis or interpretation of the data, those individuals should be asked to respect the confidentiality of the data.
  4. Members of the Collaboration should not present unpublished experimental results in seminars or conferences until (a) a memo has been circulated to the Collaboration giving details of the analysis and results, and (b) a rehearsal has been held in front of several members of the Collaboration, including a Council member and, if possible, the Spokesperson. In particular circumstances the Spokesperson may waive both these requirements.

    The Spokesperson will be designated as the Talks Coordinator. He will strive to distribute speaking invitations received by the Collaboration on the basis of the suitability of the speaker to the topic and an equitable distribution of talks to individuals and institutions with appropriate consideration of regional distinctions. As an aid to this end, he will maintain a record of all talks; thus members of the Collaboration who receive personal invitations to give talks should inform the Talks Coordinator. Speakers are encouraged to deposit a copy of their transparencies in a file which will be maintained by one of the secretaries.

  5. A paper should not be submitted to a scientific journal until the above requirements have been met and (c) a not-far-from-final draft of the paper has been discussed at a general meeting, and (d) the final draft has been circulated. After the discussion of the not-far-from-final draft, an ad hoc committee may be appointed by the Spokesperson to facilitate the preparation and submission of the final draft. This committee would consist of the principal authors and one or more individuals not directly working on the analysis. It would be empowered to adjudicate disagreements on details of the paper. In addition, the Spokesperson will maintain the list of publications.
  6. The Spokesperson will maintain the Collaboration's current author list. In general, the authors of papers will be those collaborators who have contributed to the taking or analysis of the data reported in the paper. In recognition of their contributions, collaborators who have worked on the installation of new equipment but have left the Collaboration prior to the taking of data will be included on the initial papers of the Collaboration using that equipment. Normally individuals are dropped from the general author list one year after they leave the Collaboration; however, individuals who have made special contributions to a given topic, either in hardware or analysis, should be retained on the author list of papers for which their contributions are relevant. Technical papers need only list as authors those individuals who contributed to that project, but the "STAR Collaboration" should be acknowledged. Decisions on the inclusion of authors will be done on the basis of these guidelines by the Council member from the author's institution with the concurrence of the Spokesperson.

    The authors of papers will be listed in alphabetical order, preceded or followed by the phrase "STAR Collaboration". Papers which result from student's theses should be so indicated by appropriate footnotes. Papers for conference proceedings are normally submitted in the speaker's name, plus other major contributors if appropriate, plus "STAR Collaboration", and require only the Spokesperson's agreement on the wording of the text.

  7. The Spokesperson will maintain a list of students' thesis topics which will be updated at collaboration meetings. The Council may aid in resolving any conflicts.
  8. Members of the Collaboration should not issue press releases or call press conferences without the approval of the Spokesperson, who will consult with the members of the Council.

Last-year's BUR and CAD projections

Lambda/Lambdabar polariation at 27GeV

Subsequent meeting with Berndt after the NSAC meeting in March 23 about 
Run17: Berndt said that after discussion with DOE and BNL management,
it is likely that 19 cryo-weeks of RHIC operation should be taken as baseline,
this should include two weeks of CeC commissioning.
That means effectively 17 cryo-weeks for run 17. 

Executive Summary: 

The STAR Collaboration makes the following two-year beam-use proposal, in order to achieve its spin and relativistic heavy ion physics goals on a timescale consistent with intense international interest and competition in these areas, as well as to utilize RHIC beams effectively, taking full advantage of recent improvements in machine and detector capability.

Table  STYLEREF 1 \s 1‑ SEQ Table \* ARABIC \s 1 1: Scenario I: 19 cryoweeks for Run 17 and 13 cryo-weeks for run 18. We assume most of the TPC bandwidth (1800Hz) is for the minbias event rate for isobar data-taking with 90 hours per week of DAQ time. All luminosities requested are actual sampled luminosity. See text for details of HFT and pp510 run conditions and optimizations.

 

STAR’s highest scientific priority is the first significant measurement of the sign change of the Sivers’ function, when compared to the value measured in SIDIS, and evolution effects in transverse momentum distributions through measurements of single spin asymmetries in W+/-, Z, direct photon and Drell-Yan production in transversely polarized √s = 500 GeV p+p collisions. The sign change measurement is a fundamental test of QCD and is being pursued by other experiments, making a timely measurement imperative.

 

STAR’s second scientific priority is to clarify the interpretation of the observed signatures of the chiral magnetic effect, chiral magnetic wave and chiral vortical effect by making measurements that disentangle signal from background v2 effects.  We request a 3.5 week run each for Ruthenium-96 (Ru+Ru) and Zirconium-96 (Zr+Zr) collisions in run 18.  This choice of nuclei is ideal as it allows for a variation in magnetic field at a maximum of 10%, while keeping nearly all other parameters the same. This decisive measurement of the ratio of charge separation in the isobar reduces the flow background dramatically, and will greatly advance our understanding of the chiral magnetic effect, which has fundamental impact beyond the field of high-temperature QCD.

Our next scientific priority is to take data at beam energies that are lower than the nominal energies, but are not part of STAR’s proposed Beam-Energy-Scan Phase-II program. There are two programs in our requests in this category:

a)     Au+Au collisions at 62 GeV for measurements of inclusive jets and charm spectrum at low energy. With newly developed analysis techniques, inclusive jet measurements are possible with minimum-bias data in Au+Au collisions. We have recently extended the measurement to Au+Au at 62 GeV with limited statistics from run 10. We request 4 weeks of Au+Au collisions at this energy for an inclusive jet RCP measurement. This will also provide a measurement of Non-photonic electrons from charm semileptonic decays. In addition, with the significant reduction of material from run 16 to run 17 and run 18, dilepton measurements with good statistics are possible in 4 weeks of data-taking.

b)     STAR has observed an exciting new effect, the global polarization of hyperons in noncentral Au+Au collisions. Theorists are excited and BES-II (2019-2020) will provide opportunities for higher precision explorations of the effect. There is also a possibility of observing a difference in Lambda and anti-Lambda polarization if the global polarization effect connected to the Chiral magnetic effect. We propose to extract important information from this effect at beam energy above the nominal BES-II energies through a high-statistics dataset at 27 GeV. It will be even better if we are able to collect this dataset in run17 with sufficient beam time, which allows us to analyze the effect with high statistics and guide our future direction in this subject ahead of the BES-II program.  

 

The STAR Collaboration presents in this BUR five compelling and prioritized scientific programs for the 2017 and 2018 RHIC runs, prior to the start of BES-II [[i]]. In this BUR we furthermore discuss the highlights from the scientific publications, on-going analyses and detector performance from recent runs. We also outline the planned upgrades in the next few years in preparation for Run 17 and the Beam Energy Scan II.

PAC talks

 PAC talks: 

1) run14/15 experimental results and status (Frank) 

2) BUR (Zhangbu)

3) BES-II and iTPC upgrade (Helen+Flemming)

It will be good if we can have a preview of the RHICf (Sako, Itaru), Spin (Carl) and CME (Paul) talks.

computing and calibration

 Producing the requested data for physics will involve significant use of data stores, considerable processing time, and time spent understanding and completing calibrations. When a dataset is a continuation of a collision species and energy from a previous year (with STAR's detector similarly set up), first-physics calibrations for the highest priority dataset typically require on the order of two months after the conclusion of data-taking for that year. Subsequent dataset calibrations for a given year need another month each. The proposed 500 GeV p+p and 27 GeV (and potentially 62 GeV) Au+Au datasets will be such continuations, adding to what were acquired in 2013 and 2011 (2010) respectively (repeating the environment of no HFT and no iTPC). Understanding features of new running conditions could extend calibrations of the isotope datasets to take a few months more, and it is important to keep in mind that unforeseen peculiarities of any given data set can further delay delivery. 


Table X presents estimates of the DAQ and data summary ("MuDst") dataset sizes of the proposed colliding species, along with projected single-pass production times on 100% of STAR's 2016 allocation of the RACF computing farm. It is critical to emphasize that these numbers are tied to the proposed event goals, and would scale with the actual events acquired. These productions will need to balance computing resource usage with prior-year datasets as well as ongoing calibrations and run support. STAR may choose, as an imaginable example, to produce Run 16 200 GeV Au+Au concurrently with the Run 17 500 GeV p+p in a 60%-40% apportionment, which would elongate the latter production to a year or more.

For the 500 GeV pp dataset, we expect 360 pb^-1 to require approximately 3.3 billion events recorded for processing.

Subject: 2014 RHIC Beam Use Requests

Dear RHIC Collaborations:

In view of the proximity of Quark Matter 2014 to the PAC meeting on June 11-13, the final version of the annual beam use proposals from the RHIC collaborations will be due on June 3, 2014. In view of the closeness of this date to the PAC meeting, and to leave the PAC members sufficient time to study the beam use requests, I urge you to not exceed this deadline. In order to permit Laboratory feedback before the proposals are finalized, I request that you send me a draft version of the beam use proposal no later than May 12, before everyone leaves for Quark Matter.

The proposals should describe and justify which beam operations you would like to see during the 2015 and 2016 runs, which are currently planned as 22 week runs. As usual, the beam use proposal should also give a brief review of recent published results and an early assessment of the success of Run-14.

Please send the proposals in electronic form to Peter Yamin, with copies to me, David Lissauer, Jamie Dunlop, and Thomas Roser.

Thanks in advance for your cooperation in this important matter.

Best regards

Berndt

Executive Summary

 

With two new major upgrades, the Heavy-flavor Tracker (HFT) and the Muon Telescope Detector (MTD), STAR Collaboration has positioned us well for leading the field in several major scientific programs in the next few years. We have maintained a similar pace in our scientific productivity and training of the next generation of young scientists for the last 15 years. To continue our excellent track record on science, we, the members of the STAR Collaboration, have recently produced a road map for our future in the form of our decadal plan, eSTAR Letter of Intent, Beam Energy Scan Phase II Whitepaper and are in the process of producing pp/pA document. This is a critical time for RHIC as a facility and STAR as a collaboration. STAR Collaboration is fully committed to our priorities based on the scientific pillars of studying QGP properties, quantifying nucleon spin structure, searching for critical point in QCD phase diagram and exploring the high-density gluon field in nuclei. A sustainable strong science program in STAR calls for realization of the proposed upgrades and substantial new initiatives, and require continuous effort and involvement from each and every collaborator. The STAR Collaboration proposes the following two-year beam-use request for RHIC run periods in year of 2015 and 2016, in order to achieve its near-term spin and relativistic heavy ion physics goals. A detailed breakdown of the proposed run periods is shown in Table.1.1.

Run 15:

 
The on-going run14 with Au+Au collisions at 200 GeV has been producing the first dataset with complete MTD and PIXEL/IST subdetectors of HFT. We have proposed a few incremental upgrades to the detectors, which are crucial components for a successful run15 scientific program. The necessary upgrades to the detectors are: refurbishing Forward Meson Spectrometer (FMS), a scintillator-based pre-shower detector in front of FMS, and Roman Pot Phase II*. These upgrades are anticipated to be ready for the run. The proposed run15 programs with p+p and p+Au collisions at Ös=200GeV provide crucial baseline measurements of charmed mesons and quarkonia. The same beam species will produce several important measurements to study the ridge phenomenon and onset of gluon saturation effect using the unique polarized p+Au collisions in a collider mode. 
 
A six-week run of p+p collisions at Ös=200GeV with longitudinal polarization will provide a data-set to further constrain the gluon polarization through inclusive jet and di-jet measurements at mid-rapidity, especially for large momentum fractions x, and constitutes the main spin physics objective for Run 15 longitudinal running. The non-zero gluon contributions to the spin structure of nucleon from double-longitudinal polarization measurement of dijet production have generated significant interests in further improving the measurements and its kinematic reach. The same run configuration also allows measures on ALL of p0 in the forward meson spectrometer to reach significantly lower x kinematics.
 
We propose a subsequent six-week run of p+p collisions at Ös=200GeV with spins transverse to their momentum direction. These p+p collisions exhibit kinematic and dynamical effects that are directly sensitive to quark transversity and partonic motion within the proton. In addition to improving the existing measurements of IFF and Collins analyses, a refurbished FMS with additional pre-shower in the front will provide clean direct photon measurements in the forward rapidity. This program is complemented by studies of polarized p+p elastic scattering and central exclusive production, in which a far-forward proton is detected intact. The relocation of the Roman Pots allows concurrent data-taking with nominal beam configuration, and enables new measurements on AN for exclusive J/Ψ production and inclusive diffractive production in p+p collisions.
 
A new program with five-week run with an integrated 300 nb-1 luminosity of ÖsNN = 200 GeV p+Au collisions with transversely polarized proton beam is proposed to follow the 12-weeks of p+p collisions. The program will address important physics, such as gluon saturation, cold nuclear effects on open heavy flavor and heavy quarkonia production, the ridge effect in pA, the Cronin effect and the strangeness enhancement in small-size systems. Utilizing RHIC’s unique capability of polarizing the proton projectile beam on heavy nuclei, the ratio of single spin asymmetries in π0 and direct photon production at forward rapidity between p+A and p+p collisions can be used to provide access to the elusive nuclear Weizsaecker-Williams (WW) gluon distribution function. The asymmetry for exclusive J/Ψ production in ultra-peripheral p+A collisions measurable with the upgraded Roman-Pot detectors in STAR will explore the generalized parton distribution function E for gluons.
 
Run16:
 
We propose a 10-week run of Au+Au collisions at at Ö`sNN = 200 GeV, integrating 10nb-1 of luminosity with rare triggers for Upsilon states, gamma-jet correlation, Bà J/y and J/y production, and 2 billion minbias events for Lc and differential study of charm flow and correlations.

A total integrated luminosity of 20nb-1 with the combination of run14 and run16 provides the necessary statistics for a measurement of three Upsilon states. We also request to collect 2 billion minimum-bias Au+Au collision events at Ö`sNN = 200 GeV in Run16. The effective figure of merit in terms of statistics for the signal increases by about a factor of 6 for low pT D0 in comparison to similar dataset taken in run14, t. This significant improvement will allow us to perform differential studies on the charmed hadron yields, flow and correlation in several centralities. More importantly, the high statistics and the improved pointing resolution for low momentum tracks will make the Lc measurement feasible (ct of Lc ~ 60 mm).

 
A 7-week run of transversely polarized p+p collisions at Ö`sNN = 510 GeV with integrated luminosity of 700 pb-1 is proposed for AN fo W± at mid-rapidity, g and exploratory DY measurements at forward rapidity. The possibility of measuring AN for DY, W+/-, Z0 Bosons and direct photons in one experiment would provide a unique world-class capability to test TMD evolution, access the Sivers function for sea quarks and test the prediction of non-universality for the Sivers function through three different processes to distinguish different underlying mechanisms.

Dear STAR Collaborators:

I am writing to announce the formation of the Run 16-17 Beam Use Request Committee. The committee is charged with providing a BUR document for RHIC run 16 and run 17 with the planned guideline of 22 cryo-weeks for run 16, and two possible options of 15 and 22 cryo-weeks for run17.

In the last BUR, STAR presented a request for run16 with 10 weeks of Au+Au at 200GeV and 7 weeks of p+p at 510GeV, envisioning a shut-down in run17 for preparation of BES II in run 18 and run 19. The current plan calls for an additional run17 with a BES II program in run 19 and run 20. Progresses in scientific results, detector developments and installations relevant to the programs in BUR should be documented. An initial draft of BUR should be available in May 10 for collaboration review, and a final version should be submitted to PAC in May 19.

The committee members are: Elke Aschenauer, Helen Caines, Dan Cebra, Xin Dong, Jim Drachenberg, Renee Fatemi (co-chair), Frank Geurts, Daniel Kikola, Flemming Videbaek, Lijuan Ruan, Alex Schmah, Ernst Sichtermann, Fuqiang Wang, Gang Wang, Nu Xu, Zhangbu Xu (co-chair).

Subject: BURs for Run 16 & 17

 

Dear RHIC Spokespersons:

 

I am writing again to update my request for the beam use requests for the coming RHIC runs.

 

In consultation with the Office of Nuclear Physics we have decided to make a change to the future RHIC run schedule. Specifically, we now plan to run RHIC in both FY16 and FY17, followed by one year (FY18) without a RHIC run during which the low energy RHIC electron cooling (LEReC) system will be installed. The high statistics Beam Energy Scan II is then planned for the years FY19 and FY20. The modified plan will allow for a less aggressive schedule of the LEReC project. It will also relax the conflict between the heavy ion and spin physics programs of RHIC that remained unresolved at last year’s PAC meeting.

 

I request that you submit the annual beam use requests by May 19, 2015. The BURs should be for a 22-week RHIC run in FY16, and either a 15-week or a 22-week RHIC run in FY17.

 

I also ask the STAR Collaboration to present the iTPC proposal to the PAC and to provide an update on experimental efforts aimed at exploring possible phenomenological manifestations of the chiral magnetic effect.

 

Both collaborations should present a tentative schedule for the release of results from the data taken in runs 13 and 14 (p+p, Au+Au 15, Au+Au 200, 3He+Au).

 

Thanks, Berndt

Au+Au 200GeV

Last BUR under the assumption of 22 cryo-weeks for Au+Au 200 and pp510. 

run period of Au+Au collisions at at √sNN = 200 GeV, integrating 10 nb-1 of luminosity with rare triggers for Upsilon states, gamma-jet correlations, B->J/ψ and J/ψ production, and 2 billion minbias events for Λc and differential studies of charm flow and correlations. A total integrated luminosity of over 20nb-1 with the combination of run14 and run16 provides the necessary statistics for a measurement of each of the three Upsilon states. We also request to collect 2 billion minimum-bias Au+Au collision events at √sNN = 200 GeV in Run16. A new set of the inner HFT (PXL layers) with Aluminum cables will be installed for run16 with significantly reduced multiple-scattering. We have also proposed to improve the effectiveness of online vertex selection of collisions within the HFT fiducial coverage. The effective figure of merit in terms of statistics for the signal increases by about a factor of 6 for low pT D0 in comparison to the dataset taken in run14 due to reduced cabling material and improved online vertex selection. This significant improvement will allow us to perform differential studies on the charmed hadron yields, flow and correlations in several centralities. More importantly, the high statistics and the improved pointing resolution for low momentum tracks will make the Λc measurement feasible (cτ of Λc ~ 60 μm).

Table 1 1: Scenario I-A: 22 cryoweeks for Run 17 with Isobar sources (Zr, Ru)

STAR’s top priority is to capitalize on the successful installation and operation of the Heavy Flavor Tracker (HFT) and Muon Telescope Detector (MTD) in runs 14 and 15. We request 13 weeks of Au+Au collsions at √s = 200 GeV to collect rare triggers for Upsilon states, gamma-jet correlations, B-->J/Psi and J/Psi production, as well as 2 billion minbias events for Lambda_c and differential studies of charm flow and correlations. The combination of the run 14 and run 16 will allow for measurements of each of the three Upsilon states. The heavy flavor and quarkonium program must be completed to fulfill STAR’s scientific program with the newly HFT and MTD upgrades before BES-II.

STAR’s second priority is to make the first significant measurement of the Sivers sign change and non-perturbative evolution effects in transverse momentum distributions via reconstruction of W+-, Z, direct photon and Drell-Yan single spin asymmetries in transversely polarized √s = 500 GeV p+p collisions. The sign change measurement is a fundamental test of QCD and is being pursued by other experiments, making a timely measurement imperative.

STAR’s third priority is to clarify the interpretation of the observed signatures of the chiral magnetic, wave and vortical effect by making measurements that disentangle signal from background v2 effects. We request a 3 week run each for Ruthinuium (Ru+Ru) and Zirconium (Zr+Zr) collisions. This choice of nuclei is ideal as it allows for a variation in magnetic field at a maximum of 10%, while keeping nearly all other parameters the same. This decisive measurement of the ratio of charge separation in the isobar while reducing the flow background to minimum will greatly advance our understanding of the chiral magnetic effect and has fundamental impact beyond the field of high-temperature QCD.

Table 1 2: Scenario I-B: 22 cryoweeks for Run 17 for the case where the Ru-96 source cannot be procured. 

Our next priority is to take data at lower beam energies. There are two programs in our requests in this category:
a) Au+Au collisions at 62 GeV for measurements of inclusive jets and charm spectrum at low energy.
With newly developed analysis techniques, an inclusive jet measurement is possible with minimum-bias data in Au+Au collisions. We have recently extended the measurement to Au+Au at 62GeV with limited statistics from run 10. We request 4 (5) weeks of Au+Au collisions at this energy for an inclusive jet RCP measurement. This will also provide a measurement of D0 spectrum from HFT.
b) d+Au and p+p collisions at low energies for study of onset of high-pt hadron nuclear modification due to jet quenching.
STAR has produced a systematic measurement of RCP of inclusive hadrons as a function of momentum from all the beam energies taken at RHIC. The data has shown a systematic increase of RCP from less than unity to significantly above unity when the beam energy varies from top energy of 200 GeV to 7.7 GeV. A combination of d+Au collisions and p+p collisions at energies where RCP is around unity will help us address the onset of final-state hadron suppression.

Table 1 3: Scenario II: 15 cryoweeks for Run 17 (assume Isobar sources not possible in run16)

In this beam use request the STAR Collaboration presents five compelling scientific programs for the upcoming RHIC runs 16 and 17. We discuss the highlights from the scientific publications, on-going analyses and detector performance from recent runs. We have also outlined the planned upgrades in the next few years in preparation for the Beam Energy Scan II.

Chiral Magnetic Effect theory and data projections

Hi, Zhangbu and all

I've received the magnetic field calculation results for isobar collisions from the theorists, http://www.star.bnl.gov/protected/bulkcorr/rexwg/flow/Parity/CuAu/By_cent.pdf

and I made a projection of our measurements.
http://www.star.bnl.gov/protected/bulkcorr/rexwg/flow/Parity/CuAu/PlotIsobar.gif

If we have 250M minbias events in each case, there will be a sweet zone of 20-50% centrality,
where the difference between Ru+Ru and Zr+Zr is a 3 sigma effect (combining centralities).

Hi Zhangbu and All,

 

Below is the list of analysis topics (and presentations) from14.5GeV Au+Au collisions. I have divided those topics into four groups, according to their phsics relevance. Roughly, about 50% of these topics are close to the end the analysis phase, however, almost all of them are awating for the results of the 14.5 GeV embedding.

 

As many of you know that we will have our first discussion (via BlueJeans) on the 14.5GeV data analysis status next Monday, April 20th. After the meeting, we plan to prepare for a summary including the “status/problem/plan for presentation and paper” for all topics.

Attached are ratio plots from theory calculations. The total charm cross-section is down by a factor of 4-5. However the pT dependence is not trivial.

The pT of charm quarks is, consequentially, harder at 200 GeV. For R_cp measurement it means a factor of 15-20 drop in cross-section in the interesting pT region (4-10 GeV/c).
For NPE v2 the harder spectra at 200 GeV implies that the NPE cross-section is down by a factor of 10 at low electron pT due to the feed down from higher pT.

Regarding the background, the NPE background is down by only a factor of 2 (with some pT dependence) from 200 to 62GeV.

Taking the projections for top energy of min/max = 2.2 nb^-1/ 3.6 nb^-1  /week (take the middle, say 3 nb^-1) at 200 GeV, then scaling down by E^2, would expect
~1.5 nb^-1 in such a run, delivered.  Take 70% live, ~1 nb^-1.

So a factor of 5 or so possible vs. what was triggered in Run 10, also perhaps somewhat better with a narrower vertex distribution.
Not clear whether that pushes us over the top to make the HT trigger useful. It is unlikely, especially with the worse NPE S:B with the HFT.

Raw inclusive electron spectrum from Run 10 data:

Charm cross section in p+p 200 GeV vs p+p 62.4 GeV

I believe there is an error in table 5-2. Isn’t CME supposed to be larger > in Ru+Ru and Zr+Zr? It’s listed as smaller < now.

Hi Zhangbu (cc Renee and Elke):

 

I've made it through Sections 1-3 of the Version 12 draft BUR.  I systematically tried to ignore minor typos, etc., that the PAC members should be able to read over easily.  With that "constraint", I only have a few comments or suggestions so far:

 

--  General remark:  The "Highlights" section is written in a very brief style.  That's a good thing!  But it means the knowledge that the PAC members bring to the document will be critical for them to understand everything that's discussed.  (I admit that I had difficulty following some of the heavy ion highlights.)  During your PAC talk, I could imagine that you might get one or two "what's this mean?" questions from members who had their interest tweaked by some figure.  Be prepared.

 

--  Pg 13, Fig 2-9 caption:  j_T is ~ Delta R * z * pT_jet.  (The "* z" is

missing.)

 

--  Pg 16, 2nd last line:  "... into a new ERA of lower x ..."  (Admittedly, this is just a typo.  But I simply couldn't read past it!)

 

--  Pg 33:  The upper paragraph says Fig 3-2 is from p-Au running.  The figure caption says it's from p+p.  I suspect the figure caption is correct.

 

--  Pg 36:  At present, there is nothing in Sect 3.2 "Dataset for inclusive jet and dijet A_LL".  I'm probably the internal expert here.  Should I prepare a brief paragraph and update our standard Runs 9+15 projection plot for insertion here?

 

I'll drop you another note after I've made it through the Runs 16&17 requests sections.  I might (or might not) also have some retrospective suggestions for the Executive Summary at that time.

 

Carl

A call for the annual Beam Use Request (BUR) has been sent from the BNL ALD to RHIC collaborations on February 22nd, 2017:

Dear RHIC Spokespersons:

I am writing to request that you submit the annual Beam Use Request for the RHIC runs in 2018 and 2019 and related material.

We current[ly] anticipate, assuming favorable budget conditions, runs of 15 cryo-weeks (including 2 weeks for the Coherent electron Cooling test)

in FY2018 and 24 cryo-weeks each in FY2019 and FY2020. Less favorable,

but still likely, budget conditions would only allow for a combined run of 20 cryo-weeks in FY2019/FY2020. The beam use request should consider both possibilities.

The submissions are due by May 15, 2017. Since PHENIX has ended data taking and sPHENIX has not yet started construction, I expect to receive a BUR from STAR only.

I also ask STAR and PHENIX to report on the status of analyses of data from previous RHIC runs, especially the runs in 2014-16.

In addition, I invite the STAR and sPHENIX Collaborations to present letters of intent for proposals of modest forward upgrades to their detectors for data taking after 2021 for consideration by the PAC.

The dates for this year’s RHIC PAC meeting are June 15-16, 2017. A list of current PAC members is attached for your information.

Thanks in advance,

Berndt

upgrade comments

Flemming

I can certainly do the iTPC and eTOF; In the previous BUR the upgrade parts are actually quite short 
e.g. the fpost just one-half page with layout. the BES_II stuff ~ 2 pages

I would suggest possibly the following:

Have a brief intro that shows the upgarde in the star detector context (one nice overview figure that is used ofte
here we could show one of the acceptance plots that shows what iTPC and eTFO brings acceptance

For iTPC 1 page
— brief description, status readiness for run-19
    picture of prototype from SDU, 

for EPD
since its coming up for run-18 some more info maybe 1.5 -2 pages

pics: detailled layout, picture of 1/8 quadrant installed, a simple performance plot from this year
The effect of improvement in event plane response realy is for the physics performance plots, that has such included.

eTOF one page
placement, status, performance


Rosi
That sounds reasonable.  Yes, I think an overview would show the
picture of STAR with all the detectors included + additional PID
acceptance gain since that is the point.

It should be rather easy to write a couple pages on the EPD with the
performance figures.  We have the performance improvement figures in
our proposal already, and then with something from this year's data
that should be good.

Will the etof have any performance plots from this year?

Perhaps we can pick one of the observables from BES I and show the
improvement with all three detectors.  Alex had already done something
like this for the lambda polarization (since I end up listening to
Mike a lot this is the one I'm most familiar with).  Though perhaps
this would be more appropriate in the sections discussing the physics.

Dear Helen & Zhangbu:

I am writing to solicit the STAR beam use requestDear Helen & Zhangbu:
 
I am writing to solicit the STAR beam use request for RHIC Run-19
and to request presentations from the RHIC collaborations at this
year’s PAC meeting, which is scheduled to be held on June 7-8, 2018.
 
We anticipate the 2019 RHIC run to constitute the first year of a
two-year high statistics beam energy scan. The 2017 PAC assigned
highest priority to proposed Au+Au runs at 11.5, 14.5, and 19.6 GeV, 
interleaved by brief fixed target runs at the same beam energies, as 
well as dedicated fixed target runs corresponding to CM energies of 
7.7, 6.2, and 5.2 GeV. The PAC tentatively recommended Au+Au runs in 
the collider mode at 9.1 and 7.7 GeV during the 2020 RHIC campaign.
 
The STAR collaboration should not simply take these tentative 
recommendations as a given, but reconsider and justify the prioritized 
set of beam energies and the requested accumulated statistics at each 
energy, assuming either 24 cryo-week runs or 20 cryo-week runs in each 
of the years 2019 and 2020.
 
The beam use request should be submitted no later than May 1 in order 
to allow the PAC members to study it in detail before the meeting.
 
In addition to the STAR beam use request, I would like to request
updates from STAR and PHENIX on the status of results from Runs 14-17 
(14-16 for PHENIX).
 
Best regards
Berndt

Dear Helen & Zhangbu:
 
I am writing to solicit the STAR beam use request for RHIC Run-20
and to request presentations at this year’s PAC meeting, which is 
scheduled to be held on June 10-11, 2019.
 
The 2020 RHIC run will be the second year of the planned three-year
high statistics beam energy scan. The 2018 PAC tentatively assigned 
first priority for Runs 20-21 to data taking in the collider mode at 
7.7, 9.1, and 11.5 GeV CM energy, accumulating at least 100M, 160M,
and 230M min bias events, respectively. Second priority was assigned
to fixed target runs at 3.0, 3.2, 3.5, 5.2, and 6.2 GeV CM energy, 
acquiring at least 100M events at each energy, but did not specify 
exactly in which order these data should be taken, except that 
optimal use should be made of the availability of electron cooling 
to enhance the luminosity.
 
The STAR collaboration should not simply take these tentative 
recommendations as a given, but reconsider and justify the 
prioritized set of beam energies and the requested accumulated 
statistics at each energy, assuming either a 24 or a 28 cryo-week 
run in FY2020, followed by a 20 cryo-week run in FY2021. STAR should
also consult with C-AD about the number of dedicated LEReC 
commissioning weeks that are expected to be required during Run-20.
 
In addition, I request presentations on (i) the status of data 
analysis from previous RHIC runs and (ii) an update of the physics
goals for a short (16 cryo-weeks) forward Spin physics run in FY22 
with 500 GeV p+p collisions. 
 
The beam use request should be submitted no later than May 15 in 
order to allow the PAC members to study it in detail before the meeting.
 
Best regards
Berndt

BNL Nuclear Physics PAC 2023 Charge and Agenda

 
*sPHENIX: Beam Use Requests for Runs 24-25
*STAR: Beam Use Requests for Runs 24-25

The Beam Use Requests should be submitted in written form to PAC by August 11, 2023 by emailing Fran and copy Haiyan and John the BUR directly or provide a link to access the BUR before the due date.

The BURs should be based on the following number of cryo-weeks. For Run 2024, we ask that you consider three scenarios for 20, 24 and 28 cryo-weeks each, given the uncertain budgetary situation. For Run 2025, the first number is the proposed RHIC run duration for scenario 1 and the second number corresponds to optimal duration (scenario 2) presented to the DOE-ONP in BNL’s FY25 Lab Managers’ Budget Briefing:

2024: 20/24/28
2025: 24 (28)
 

Note the eventual running cryo-weeks for each run will depend on the final budget guidance for that year.

Background Materials

Timeline

  • committee review: October 28, 2024 
  • draft document to Collaboration: October  30, 2024
  • final version to ALD: Novemer 3, 2024
  • NPP 2024 PAC Meeting: November 7-8, 2024


BNL Nuclear Physics PAC 2024 Charge and Agenda

The run scenarios for Run 25 (FY25) to consider:
• 20-week operation (instead of 22-week guidance because 2 weeks already
taken by Run 24)
• 28-week operation assuming we can extend the run. (I will talk to CAD &
EIC about possible a further operation and its consequences).

Timetable for the BUR 2025/26
• End of Run 24 – October 21, 2024
• CAD provides guidance for performance by October 28, 2024
• Experiments finalize and submit the BUR to me/PAC by November 3, 204.
• PAC meets on November 7, 2024
