Below is a table with the datasets planned for MDC4.
|
Dataset A |
Dataset B |
System | Au+Au | p+p |

# of Events | 20,000 | 100,000 (without pileup) |
Geometry | y2001 (i.e. exact configuration for run 2001) | y2001 |
Simulator | TPC = TRS, SVT = fast, RICH = RRS, EMC = standard, FTPC = slow, TOF = fast (in progress) | same as in Au+Au |
Field | 0.5 T | 0.5 T |

Flow | v2 pT dependent, slope: v2 = 0 for pt = 0 GeV/c v2 = 4% for pt = 0.5 GeV/c flat in eta (4%) v1 = 0 for pt = 0 GeV/c |
N/A |
Add-on | 3 pi0 / event, flat in 2 GeV/c < p < 15 GeV/c 50 Omegas/event (decay in GSTAR) 50 L(1520) -> p K 50 Sigma(1385) -> L pi 10 J/Psi -> e+ e- / event (decay in MEVSIM) 10 phi -> e+ e- / event (decay in MEVSIM) 10 Uspilons -> e+ e- / event (decay in MEVSIM) 10 D0 -> K pi/event (decay in GSTAR) 10 D+/- -> K pi pi /event (decay in GSTAR) |
