  2. General parameters Requested by: Spin group(Matt,Jim,Jan) Reasoning: - SimTag : rcf9041 Task: Spin Study Beam: PP500 Vertex: <X>= 0 σx = 0.4 <Y>= 0 σy = 0.4 <Z>= 0. σz = 25 Zcut = +- 10 (???) EtaCut = +-6 StarSoft local

  3. Generator Generator: Pythia Control file: Please check it carefully. It is from jet request ENER 500.0 ! 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 !

  6. Resources • Lidia estimated: • - pp 500 GeV, pythia with year 2009 geometry - 2.3M events;   we don't have any example for pp 500GeV but we can suppose   that resources will be doubled, in this case it requires: • fzd = 600GB; • reco = 1.2TB; • CPU ~ 18000 hours for reco + ~50% for simu; • total CPU ~ 27000 hours(3.2 years); • total size ~ 1.8TB; StarSoft local

  7. Geometry • Geometry y2009 StarSoft local
