  2. General parameters Requested by: JLC PWG - Jana/Joern Reasoning: Needed for QM SimTag : rcf9001 Task: Jet Study Beam: PP200 (imitation of jets AuAu200) Vertex: <X>= 0 σx = 0.01 <Y>= 0 σy = 0.01 <Z>= 0. σz = 60 Zcut = +- 30 StarSoft local

  3. Generator Generator: Pythia Control file ENER 200.0 ! Collision energy MSEL 1 ! Total cross section, i.e. elastic+inelastic D=1 * caution -- Pt bin CKIN 3= 35.0 CKIN 4= 45.0 MSTP (51)= 7 MSTP (81)= 1 MSTP (82)= 4 PARP (82)= 2.0 !- PARP (83)= 0.5 !- PARP (84)= 0.4 !- PARP (85)= 0.9 !- PARP (86)= 0.95 !- PARP (89)= 1800 !- StarSoft local

  4. Generator Control file continue PARP (90)=0.25 PARP (91)=1.0 !- PARP (67)=4.0 !- *Make the following stable: MDCY (102,1)=0 ! PI0 111 MDCY (106,1)=0 ! PI+ 211 MDCY (109,1)=0 ! ETA 221 MDCY (116,1)=0 ! K+ 321 MDCY (112,1)=0 ! K_SHORT 310 MDCY (105,1)=0 ! K_LONG 130 MDCY (164,1)=0 ! LAMBDA0 3122 MDCY (167,1)=0 ! SIGMA0 3212 MDCY (162,1)=0 ! SIGMA- 3112 MDCY (169,1)=0 ! SIGMA+ 3222 MDCY (172,1)=0 ! Xi- 3312 MDCY (174,1)=0 ! Xi0 3322 MDCY (176,1)=0 ! OMEGA- 3334 StarSoft local

  5. Statistics • Total 4.2M events • Statistics for the partonic pT bins: • 3- 4 690k • 4- 5 686k • 5- 7 398k • 7- 9 420k • 9-11 412k • 11-15 420k • 15-25 397k • 25-35 400k • 35-45 120k • 45-55 118k • 55-65 120k StarSoft local

  6. Geometry • Geometry y2007g StarSoft local

  7. Resources Lidia estimated: • pp 200GeV, pythia with year 2007 geometry - 4.2M events; • total size ofr *.root 1.1TB; • fzd 589GB • CPU = 17500 hours for reco, ~50% for geant simulation; • total CPU ~26250 hours; • total size ~ 1.7TB; StarSoft local

  8. Approved by PWG Dear Victor, I have checked the parameters for pythia+geant Jet requests (Run7 and Run8) and they are OK.        With best regards, Jana. StarSoft local
