Generator

  • physics:
    • define samples - ok for now:  
      • DBD 250 GeV + 6f
      • general purpose Bhabhas / BSM signals etc. => later...
      • 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: see table by Junping, basically 10ab-1.
      • still iterate on very high-rate processes (aa→2f, ae→3f, etc)
      • Radiative return to Z events: Generate inclusive 2f as before, plus dedicated samples later eg with photon in ME
    • Naming convention of whizard2 samples and directory structure → ok up to 4f, iterate 6f

      • all bWbW => "ttbar"

      • WW/ZZ/ WWZZ etc needs fleshing out
  • general:
    • verify batch mode - done, apart from splitting single channel into several jobs

      => Whizards need to implement input of start event number > 1
    • tagged Whizard version => hoping for 2.8.3 in a week or two...
  • ee: 
    • generate events
      • 2f (need splitting functionality, s. above)
      • 4f
      • 6f (define structure, s. above)
  • ea / ae / aa:
    • create lumi spectra  and z-position of vertex distributions => done
    • more studies: phase space splitting between Zee and aa->2f
    • generate events: very high-rate processes, s. above
  • aa overlay : => produced, on Dirac
  • seeable pairs:  fine, on Dirac

Simulation

Reconstruction

  • muon reconstruction failure at costheta = 0.6   => fixed by Remi
  • photon cluster position / angle bias  => theta "just" a calibration/correction issue,   phi unclear? => gave up
  • photon energy calibration consistent with Pandora calibration
          => seems to be ok as verified by Remi
  • z0/d0 errors in fwd region => what was this about? => gave up
  • tune BeamCal reconstruction → done
  • calibrate LumiCal & LHCal => not done
  • update parameters for beam spot constraint (LCFI) ???
  • validation: ongoing ....

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)
  • Installation of DESY new disk - done
  • 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? => to be discussed, JL's understanding was we aim for numbers in JT's table for DSTs, while keeping only small fraction of REC evts

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=> Confirmed(Akiya)
    • Update for new directory structure and file name conventions.
      → Revisit file name convention : "wizard2" as "w2"? 
      ==> (Akiya) Same as the previous productions. Namely no generator name in production files.
    • simulate aa_lowpt and seeable pair background files. Update scripts to 250 GeV background files.
      ==> (Akiya) Small number of background files will be produced with ILCSoft/ILDConfig v02-00-02, for validation.(Done. 100evtsx20files produced)
  • Need small whizard2 samples of various process type for development of production scripts.
              ==> (Akiya) Small samples (2f, 4f, aa_2f, 3f/5f ) have been produced.  Modifying production scripts to adapt new naming convention.
  • Save tar-gzipped log files on tape directory.
  • File save location : DESY-SRM as primary and KEK-SRM as secondary.
  • BG samples situation
