Some findings

CMKIN

• Datacard parameters
  MSTJ(22)=2
  A particle is decayed only if its proper lifetime is smaller than PARJ(71), which is set to cτ = 10 mm. Strange particles are "stable", charm and bottom decay.

OSCAR

• Simulate tracker only
  • Use reduced geometry file
• Simulated V0 daughters
  Mantis/MantisApplication: add to src/NewTrackAction.cc

#include "G4VProcess.hh"
// Lengths are in mm for OSCAR!
if( (aTrack->GetCreatorProcess()->GetProcessType() == fElectromagnetic &&
     aTrack->GetCreatorProcess()->GetProcessName() == "conv") ||
    (aTrack->GetCreatorProcess()->GetProcessType() == fDecay &&
     aTrack->GetCreatorProcess()->GetProcessName() == "Decay") )
  if(fabs(aTrack->GetPosition().z())    < 50. * 10 &&
     fabs(aTrack->GetPosition().perp()) < 15. * 10)
    trkInfo->storeTrack(true);

Mantis/MantisApplication: add to BuildFile

 <use name=geant4>
 <use name=clhep>

compile in Mantis/MantisApplication/src
scramv1 build

• If an oscar job fails (exceeds the max cpu time, or lose terminal connection etc), just copy the content of the nameoftherun.runid file (

  CARF:ResumeRun= @{[ ... a huge hexadecimal string ... ]}@

  ) to the end of the .oscarrc file, and run again. The simulation should continue from the last successful event.

ORCA

• Compilation
  • TrackerReco/PixelTrackFinder: add to src/SeedGeneratorByRecTracksRecAlgo.cc
    #include "CARF/Reco/interface/RecConfig.h"
  • TrackerReco/TkEvent: add to interface/TkSimEventDispatch.h
    #include "TrackerReco/TkEvent/interface/TkSimEvent.h"
  • To skip cache scan:
    scramv1 build --fast
• SimTrack filtering
  • TkEvent/src/SimpleCarfSimTrackFilter.cc: change the condition

    theSimTrack.charge() != 0
