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

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.
