Generator

  • physics:
    • define samples:  
      • DBD 
        + WIMP analysis samples (signal & background)?
        + Higgsinos? Jackies or Hales?
      • aa→2f for SGV processing?
      • how about 6f? Not generated for DBD at 250 GeV, but processes like WWZ and vvWW etc should in principle be open?
      • general purpose Bhabhas?
      • cross-section validation => ongoing with Junping
  • general:
    • verify batch mode
    • set up 6f ?
  • ee: 
    • generate events
  • ea / ae / aa:
    • create lumi spectra
    • generate events
  • aa overlay ?
  • seeable pairs => Mikael says is done (99% CL), maybe not on Dirac?

Simulation

  • selection / adjustment of DD4HEP detector model
    • vertex detector?
    • validation!
  • create ddsim steering / config files for 250 GeV => ask Remi
  • z vertex distributions for ee / ea / ae / aa => MIkael checks whether he has the numbers, then need to be put in ILDConfig
  • verify that photon cluster position effect is not due to cell geometry problem   => expected? Then calibration issue?
  • simulate full pairs     => ask Daniel             => tune BeamCal reco!
  • simulate seeable pairs
  • simulate aa overlay
  • simulate single particles for calibration   => verify that LumiCal / LHCal are covered!

Reconstruction

  • solution unknown:
    • muon reconstruction failure at costheta = 0.6   => needs 4 FTE weeks
    • photon cluster position / angle bias  => possibly "just" a calibration issue?
    • photon energy calibration consistent with Pandora calibration
    • z0/d0 errors in fwd region => on a good way, fix requires time?
  • solution / procedure known:
    • tune BeamCal reconstruction
    • calibrate LumiCal & LHCal
    • update parameters for beam spot constraint (LCFI)
  • validation!

Production

  • DISK SPACE ! (Cannot use tape back-end anymore) => estimate need: 100-200 TB, check!
  • save REC files only for 10% of events
  • update production scripts

Solved issues (for new productions)
