Summary of W M-C request for APS 

(updated Jan 8, 2010)

Requirements:

• library SL09g, no filtering
• Pythia 6.4.22,  p+p 500 GeV
  • Tune 320: “Perugia 0” , http://home.fnal.gov/~skands/slides/pythia-atlas-mar09.pdf
  • no phase space restriction (interaction w/ the beam pipe will cause more secondaries) 
  • eta, phi ranges - do not constrain. For Z,W production the x-section dies out quickly w/ eta, minimal CPU benefit 
• STAR geometry y2009a, low_sim option for both EMCs, reverse full field
• TPC gains as for 'low HV' working point during pp500 run
• TPC status tables: actual dead padrow map for selected time stamp(s)  (TBD 10 time stamp values)
• TPC dEdX similar to real data calibration (low HV) with 10% accuracy
• not possible: TPC points corrections compatible with :"Corr4,OSpaceZ2,OGridLeak3D"
• Beam line offset in GSTAR & BFC : one , the same fixed value for all events x=y=0. 
• Vertex distribution in GSTAR:
  • transverse : Normal(0 cm, 0.015cm) in X,Y
  • Z: Normal(x0=-2cm, sig=42cm) truncated at |Z|<120 cm
• Vertex reco in BFC : use PPV w/ beam line constrain,  allow PPV to find all vertices in the M-C event
• Pileup - do not simulate
• Important detectors: TPX (TPC w/ TpcRS), BTOW, ETOW
  • other detectors  - does not matter
• BTOW calibration set to 'sim' (ideal gains)
• ETOW calibration set to  'missetTCD' - the offline gains for pp500 in run 9 
• BTOW, ETOW pedestals - set to 0 - use 'sim' flavor
• BTOW, ETOW status table -  real ( drop dead towers according to time stamp, similar to TPC dead padrows)
• save : muDst , geant , log files, fzd, kumac

 FYI, during pp500 run we acquired LT~10/pb.
