Light Flavor Spectra Physics Working Group
In high-energy nuclear collisions, light flavored quarks (up, down, and strange) are produced in large quantities. Three major themes capture most of the topics that are considered part of the Light-Flavor Spectra Physics Working Group:
- Bulk properties of the produced particles: by measuring the momenta spectra of light-quark-flavor hadron spectra and assuming a thermalized system, we determine the system properties such as the temperature and the baryon chemical potential.
- The masses of the light flavor quarks are expected to be modified by the surrounding strongly interacting medium. While the heavy quarks (charm, bottom, and top) have masses that agree with the mass expectations from a Higgs mechanism, the light quarks appear to have gained a significant constituent-quark mass.This mechanism, the spontaneous chiral symmetry breaking, and the restoration of this symmetry is expected to occur in the hot and dense quark matter.
- Leptons are an ideal probe in determining the properties of the hot and dense medium. With only little interaction with the strongly interacting medium, electrons and muons travel practically unperturbed through it. The inclusive di-lepton invariant mass distribution contains a wealth of physics, ranging from the leptonic decay of vector mesons, to the Drell-Yan pair production, and thermal radiation processes.
In addition, this physics working group has been key in the analyses that led to the recent observations of anti-hypertriton, and anti-4He.
In what follows, we showcase in each of the main areas several of recently published results that originated from this physics working group.

1. QM readiness:
- dielectron (Shuai)
1. Current status: The UU@193GeV (MB trigger) di-electron analysis is
basically done, and the proposed physics plots have been already generated.
2. The parts not finished yet: The systematic uncertainty of hadron
contamination (will be done in one week); make the physics plots in good
shape.
3. Results I intend to show:
http://www.star.bnl.gov/protected/lfspectra/syang/conference/QM2015/Proposed_plots_for_QM.pdf
- Jet quenching S parameter (Stephen)
- Rapidity density at BES (Chris)
It contains an example of all the physics plots that I want to show:
1. Pion Spectra
2. Rapidity Density Distributions
3. Full Phase Space Yields
4. "Dale" Observable
- Rcp and strangeness (Daniel)

Embedding requirements calculation
Embedding Requirements Calculation
Here I go through a sample calculation setting out the assumptions used.
Bottom up calculation.
Define desired error
The starting point is to define what statistical error we are aiming for on the correction for a particular pt bin in a spectrum. Obviously there is a contribution from the real data but here we are concerned with the statistical error from the embedding.Say that we think a 5% error would be nice. That means that 400 reconstructed counts are required if the error is like √N. Actually is is a bit worse than that because the numerator is constructed from a more than one number with different weights so more counts are required, ~500.
Fold in likely efficiencies
The number that must be generated in that pt bin to achieve this then depends on the efficiency for that bin. For Au+Au minbias a typical efficiency plot might have efficiencies of approximately 5% for pt <1 GeV, 10% for 1 < pt 2 GeV, 15% for 2 < pt < 4 GeV and 40% for pt > 4 GeV. This is for a set of fairly loose cuts close to the default finder ones, loosening at pt=4 because the finder cuts become less stringent at 3.5 GeV.Therefore we find that the number generated per bin needs to be 10000, 5000, 3000 and 1250 in the pt ranges mentioned. Clearly the low pt part where the efficiency is lowest is driving the calculation.
Effect of choice of bin size
For these numbers to be generated per bin we can ask how many particles per GeV we need. At higher pt we tend to use 500 MeV bins but at lower pt 200 MeV bins are customary, I have even used 100 MeV bins in the d+Au analysis. Choosing 200 MeV bins leads to a requirement for 50000 particles per GeV at low pt etc. This is already looking quite like quite a large number…Binning with centrality
We embed into minbias events and we'd like to have the correction as a function of the TPC multiplicity (equivalent to centrality). Normally we embed particles at a rate of 5% of the event multiplicity. The 50-60% bin is likely to be the most peripheral that is used in analysis. Here the multiplicity is small enough that we will only be embedding one particle per event. Therefore 50000 particles per GeV requires 50000 events in that particular centrality bin. The 50-60% bin is obviously around one tenth of the total events. I don't think we have a mechanism for choosing which events to embed into depending on their centrality so it means that 500k events per GeV are required.Coverage in pt
We expect our spectra to go to at least 7 GeV so its seems prudent to embed out to 10 GeV. For Λ these data might also be used for proton feeddown analysis. This means that 5 million events are required!Coverage in rapidity.
Unfortunately we are not finished yet. We have previously used |y|<1.2 as our rapidity cut when generating even when using |y|<0.5 in the analysis so a further factor of 12/5 is required giving a total of 12 million events per species!Comments
This number of events is clearly unacceptably large. Matt has mentioned to me that we can do about 150 event per hour so this represents about 80k CPU hours as well as an enormous data volume. Clearly we have to find ways to cut back the request somewhat. Some compromises are listed below.- Cut down rapidity range from |y|<1.2 to |y|<0.7 gaining factor 12/7 ≈ 1.7 → 7 million events
- Settle for a 10% error in a bin rather than 5% gaining factor of 4 → 1.75 million events
- Hope that efficiency is not a strong function of multiplicity allowing is to combine mult. bins. Gain of factor 2? → 875k events
Strangeness Phone Meeting 2007/5/14

Working on getting v2 for the 0-12% sample. This would be for h±, use nq scaling as before to estimate Omega v2. Aihong is providing assistance. Marek. Aim is to reproduce Jana's delta-phi result but with additional anti-merging correction and to get delta-eta projections. Have switched to using 'Yale Trees' in order to go to lower pt (reprocessing through RCF was taking too long). This would be for h-h only as there is currently insufficient V0 daughter info to do the anti-merging cut for V0-h correlations. This should be about to change though. [I have that 7M out of 20M events were done already by Marek and that a new run to get a set of Yale Trees with all V0 info is ready. I assume these are two separate things.] A fall back solution of using the 'mirror image' trechnique is available [does this work for delta eta though?] Christine Working to get efficiency correction for identified associated particles (i.e. V0) Has an example code from Ant to extract efficiencies from the flat pt embedding done for Cu+Cu Currently that cover eta ±0.5 and eta ±1 is required. Will scale Au+Au embedding by result to extend to larger eta. There should anyway be new Cu+Cu embedding coming. Jiaxu Was available for the meeting (time zone issue!) but sent update later to say that he is working on using the highest pt bin (6,9) GeV and some simulations. Ant. Working to finish feed-down correction and compare with Matt's method (working out Xi eff. as a function of the Lambda pt vs scaling to the Xi distribution in embedding [this distinction needs a better explanation sometime]) Also checking the errors on dN/dy from the extrapolation of the pt spectra to pt=0. Jun. Student working on incorporating SVT/SSD into Xi and Omega analysis. Presumably not practical on the timescale of SQM though [production only just getting underway and need to develop embedding chain to include SVT/SSD] Comment from Matt. Main job is to get embedding re-run, if this is indeed necessary. Kaons.
