Comments and Common Settings Proposal

• S. Muanza

As of May 17th 2004

• Software:
• mc_runjob v06-02-08
• cardfiles v00-08-XX (or higher)
• d0_mess (p14.07.00)
• EvtGen (p14.07.00)
• New Pythia list for stable C-hadrons (cardfiles/v00-08-05/dzero/EvtGen/pythia_stable-c-hadrons.list)
• New Pythia list for stable B-hadrons (cardfiles/v00-08-05/dzero/EvtGen/pythia_stable-b-hadrons.list)
• Tauola:
• under verification: either usual BRs or Top Group setting
• Possibilty to use 2 separate taum/p.cmd files
  

• Generators: p14.07.00
• D0gstar:      p14.07.00
• D0sim:        p14.07.00
• D0reco:       p14.06.00

• MC mininum bias overlay:
• Pythia 6.2 + CTEQ5L + "Tune A"
• Poisson distributed with the conservative <Noverlay>=0.4
• No luminosity bins or profiles
• Request IDs: 11248, 12003, 12004, 12005, 12006, 12007

• Fragmentation Model:
• Pythia default Lund model (no Peterson fragmentation)

• New default for HF quark masses:
• m(t)=175 GeV (only for single or pair top events production)
  
• m(t)=178 GeV (for all virtual NLO effects: MCFM, SUSY RGEs, PROSPINO, MC@NLO,...)
• m(b)=4.75 GeV
• m(c)=1.55 GeV
  

• Mass^ (in partons hard scattering center of mass frame) bins for gam*/Z and gam+gam processes: 

• pT^ (in partons hard scattering center of mass frame) bins for continuous processes (QCD, ccbar, bbbar, gam+jets):

• ALPGEN:
• Large Alpgen+Pythia samples will be produced after we reach some conclusions on the Common Studies

• HERWIG: not part of the CS MC for this round because:
• don't have MPI (JIMMY), nor tuned UE
• no work done on new EvtGen C/B-hadrons lists
• cannot apply the new default for m(b) and m(c) in p14.07.00
