electron:

  • More elecrton candidate and seleted in Private Data, ???? vali_czhufast_ele_num_pt.gif

  • Private Data: true electron from hard process; Official: true electron after radiation vali_czhufast_electron_dist.gif

  • Same reason as above, Private: low pt electron difficult find its truth partner in hard process with $\Delta R$ constraint. vali_czhufast_electron_reco_effi.gif

muon

  • Same reason on truth muon as electron vali_czhufast_muon_dist.gif

jets

  • Truth quark not filled vali_czhufast_jet_reso.gif

  • will check for tau jets vali_czhufast_b-tag-weight.gif

measurement

  • use my private atlfast data to repeat the analysis in CSC note. (correction function from atlfast. measurement with full sim).
correction function: 1.104950+(0.052670)*x+(-1.228851)*x*x+(0.298903)*x*x*x+(0.736429)*x*x*x*x
A:  0.76034  error:  0.166607  (this is bin15, 0.68 for bin 25 means lot of effect from correction function env)
correction function: 1.002070+(-0.136806)*x
Ad:  -0.420201  error:  0.0981409
  • As known, no qq events....... in parton level, events=158508 A=0.605033,
    • measure with new approach A=0.36, mean the real physics content in full simulation is resistant to the effect of correction function. or sensitive to "new physics"
