The p11.01.00 Filter

• Aim test single muon filter without calmatch /
  central trackmatch
• with cut on muo_local pt
• with tight / loose / astub -like quality
  criteria
• Muon L3TMuon(muontrackrefsetMUO_LOCAL,
  centralmatchrefsetNONE,muocalmatchrefsetNONE)
• L3FMuon keyMuon_loose refsetMUON number1

• Out-of-boxness addpkg tsim_l3, addpkg
  run_config_mgr,
• ScriptRunner_x.rcp
• add config to packages ? use run_cfg_mgr
• remove analyze ? do not use L3Analyze, to
  prevent crash
• run_config_mgr.rcp use_database false
• make sure that cfg.dat is correct for this run /

Test Samples

• Processed following samples on a (dual) 933 MHz
  Clued0 node
• Single 5 GeV Muon MC, eta lt 4.2 5
  000 events
• Single 5-100 GeV Muon MC, eta lt 2.5 5 000
  events
• Stefans golden J/psi sample
  195 events
• Stefans golden central J/psi sample
  78 events
• Special run 14747 mu1ptaxaa only 19
  324 events
• Recent run 14890
  22 995 events
• takes 40 minutes with muon toolsfilter only
• xx minutes with CalMuo4.x trigger list (-gt from
  Volker)
• yy combined??
• --gt confirms 1.4 kB memory leak per event on data
  offline, 0 kB on MC offline ?? kB online

Conclusions

• Survived test samples ? test more with trigger
  list updates?
• Memory leak OK ? being looked at by Boris
• Timing OK, will be better ? see earlier results
  Christophe Clement
• Config.dat does the trick ? workable temporary
  solution
• Results are consistent and indicate
• good rejection factors (4 - 66 for loose) w.r.t.
  L1
• ? 50 efficiency for high pt single muons
• losses partly understood (? martins talk)
• based on MC ...
• Need some real high pt muons ? Lets collect them
