DYanalysis_asvyatko.pptxAgenda

Action items

  • Alexey: DY analysis
    • Perform closure test for muons and electrons with and without regularization
    • Look up the dielectron mass resolution results (e.g. as recently discussed on HN or H->ZZ analysis)
    • Learn from other analyses (at least 3) how the ECAL eta gap is taken into account and compare to your result and approach
    • Cross check effect of ECAL gap on efficiency: How many events we loose with the gap at 8 TeV
    • Show energy scale correction plots to EGamma POG (cc Norbert)
    • Why do we have a constant 1.1 correction above the Z peak in the ratio of pre-unfolded to unfolded yields?
    • Last bin at high mass absolute cross section: check background
    • Integrate 2D pre-unfolded to unfolded ratio plot and compare to 1D
    • Fix remaining problems of double ratio in the muon channel
    • Distribute close-to-final AN
  • Hwidong: Z' analysis
    • Send deadline and my contribution for Z' AN note
    • Send first draft of Z' SUSY AN note ASAP
    • Check natural width of the Z' MC samples (get reference from standard Z' about the mass resolution and natural mass width)
    • Run Madgraph/Herwig and make a progress on the model 2 mc generation
  • Benjamin: H → μμ analysis
    • Understand the CMS and ATLAS analyses
    • Make sure ntuples are working correctly
    • Continue to apply selection cuts to the samples and train classifiers
    • Create ratio plots with errors: Use DY plots along with uncertainties to see if analysis is viable
  • Benjamin, Hwidong: Muon HLT
    • Make sure the stepping helix propagator is not used inside tracker
    • Create a plot showing the efficiency performance of the 3 seeding algorithms vs PU (with fixed OIState)
    • Implement the new muon specific tracking parameters in the menu (use same configuration as the improved tracking group uses for our L3 trajectory building): Show differences to current L3
    • Find out why the code (to first propagate to the vertex) was implemented in the first place
    • Understand tracking regionregional tracking, track matching
