Plan for Work

To compare the distributions of some variables in samples w/outpileup for Trigger Robustness studies.

• To do this, is need identify some samples on which to make plots. Samples reconstructed from RDOs with Release 13.0.30.3 using as job option:
  • testElectronSliceAthenaModernRDO.py, where the following signatures for electrons have been fitted out:
    • "TriggerFlags.EgammaSlice.unsetAll()"
    • "TriggerFlags.EgammaSlice.signatures" = {"e10", "e25i", "2e15i", e10TRTxK","Zee", "Jpsiee"}.
• The data samples are:
  • Single particle electron without pileup:
    • trig1_misal1_mc12.007020.singlepart_e_Et780.digit.RDO.v12000605_tid013437
  • Single particle electron with pileup
    • trig1_pile1sf05_misal1_mc12_v1.007020.singlepart_e_Et780.digit.RDO.v12000605_tid013482
  • Z --> ee with pileup
    • trig1_pile1sf05_misal1_csc11_v1.005144.PythiaZee.digit.RDO.v12000605_tid009362
  • Z --> ee without pileup
    • misal1_csc11_V1.005144.PythiaZee.digit.RDO.v12003103

• The paths of these samples are, respectively (Those labeled with "D" were created by Deywis Moreno):
  • /space2/deywis/single_rel13_ESD_from_RDO/
  • /space2/deywis/rel13/SinglePileup/ntuples (D)
  • /space2/deywis/rel13/ZeePileup/ntuples (D)
  • /space2/deywis/rel13/Zee/ntuples/user.DeywisMorenoLopez.misal1_csc11_V1.005144.PythiaZee.digit.RDO.v12003103_28Feb08 (D)

Some Results

• You can find the superimposed plots for single w/out pileup
• TdIAlgo superimposed distributions for single e w/out pileup samples:
  

• T2IdPt distribution for single with/out pileup samples for Pt > 5GeV/c:
  

• T2IdPt distribution for single with/out pileup samples for Pt > 5GeV/c and IdAlgo = 2:
  

• DeltaEta distributions for single with/out pileup samples with IdAlgo=2. Computed from |T2CaEta-T2IdEtac|:
  

• DeltaPhi distributions for single with/out pileup samples with IdAlgo=2. Computed from |T2CaPhi-T2IdPhic|:
