Generator

  • physics:
    • define samples:  
      • DBD 
        + WIMP analysis samples (signal & background)?
        + Higgsinos? Jackies or Hales?
      • 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?
      • question from Daniel: status of tau polarisation in Whizard2 => can be checked on existing small test samples
        transverse tau polarisation: Akiya did some work, unclear status
    • Number of events for each processes.  Especially large Xsect. processes, such as 2f, 1f, 3f.
    • Radiative return to Z events. Generate separately or generate all process together.
    • Naming convention of whizard2 samples and directory structure → ok up to 4f, iterate 6f
  • general:
    • verify batch mode
    • tag Whizard version?
  • ee: 
    • generate events
      • 2f
      • 4f
      • 6f
  • ea / ae / aa:
    • create lumi spectra  and z-position of vertex distributions => done
    • generate events!
  • aa overlay : waiting for Tim... => remind....
  • seeable pairs:  fine, on Dirac

Simulation

  • selection / adjustment of DD4HEP detector model
    •  use the existing ILD_l5_vo2 => no validation needed
  • create ddsim steering / config files for 250 GeV 
  • z vertex distributions for ee / ea / ae / aa => Remi has put them in ILDConfig:
  • verify that photon cluster position effect is not due to cell geometry problem   => expected? Then calibration issue?
    • simulate full pairs     => done            => tune BeamCal reco!
    • need to create BeamCal bg-map for large (and small) 250 GeV models
      • w/ and w/o anti-DID
      • for standard reco use same as for 500 GeV (w/ anti-DID ?)
  • 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 =>Moritz
    • photon cluster position / angle bias  => theta "just" a calibration/correction issue,   phi unclear? => Daniel
    • photon energy calibration consistent with Pandora calibration
            => needs deep thinking on Pandora calibration strategy, Daniel will take a look once tautau benchmark is done
    • z0/d0 errors in fwd region => on a good way, fix requires time?
  • solution / procedure known:
    • tune BeamCal reconstruction → ongoing (Moritz)
    • calibrate LumiCal & LHCal ???
    • update parameters for beam spot constraint (LCFI)
  • validation!

Production

  • disk space (Cannot use tape back-end anymore) => estimate need: ~200 TB
      => mc-opt3 currently is 600-700 TB => 1 detector model = 350 TB
                     
    keep only 10% of REC files (but all SIM files) => 25% less ?
                     (hybrid simulation, reco only SiW + AHCAL)
  • Save sim files of all events, but save REC files only for a fraction of events => implemented by Akiya
  • Required statistics : 2ab-1 for each channel?
    Estimate required disk space and CPU times for required statistics.
    → How about the large cross-section channel? (2f, 4f)
    → How about the 6f samples?
  • update production scripts
    • make sure whizard2 lcio file splitting works
    • Update for new directory structure and file name conventions.
      → Revisit file name convention : "wizard2" as "w2"?
    • simulate aa_lowpt and seeable pair background files. Update scripts to 250 GeV background files.
  • Need small whizard2 samples of various process type for development of production scripts.
  • Save tar-gzipped log files on tape directory.
  • File save location : DESY-SRM as primary and KEK-SRM as secondary, need to purchase  TAPEs at KEK.
  • BG samples situation
