Monte Carlo samples for B-group

Monte Carlo samples for B-group

• Structure of realistic B-MC for 5.3.x
• Step 1
• Generation (Only Pythia and Bgenerator used to
  now)
• Simulation with Silicon clustering
• Step 2
• Trigger Simulation TRGSim_mc
• svtfilter or Prereq ? include this in
  TRIGSim_mc
• Step 3
• Production
• One tcl file, number of events, run number,
  random seeds changed by submitter. More difficult
  to re-send crashed jobs, easier to make mistakes,
  lets think about it.

Monte Carlo samples for B-group

• What we want for simulation 5.3.x
• Bgenerator fix
• EvtGen new release and new decay table
  (R.Tesarek)
• Improved COT simulationdE/dx from GEANT or from
  parametrization of different particle species
• int q stepdata.g3()-gtGckine()-gtCHARGE
• charge is calculated but not used
• XFT correct simulation of p /K (get it from COT
  ?)
• ISL/L00 tuning ??
• MC widths should match the data if 5.2.0 is used
  for data (better alignment). Probably no action
  needed on MC at present.
• In other packages
• Include svtfilter toTRIGSim_mc
• Include trigger decisions to be able to use Prereq

• Differences of COT efficiencies are not
  reproduced in MC
• p/K XFT efficiencies are the same in simulation.
• Use dE/dx in COT to calculate charge, hit and
  ToT for COTQ
