Heavy Ion July exercise

Configuration

  • CMSSW_3_6_1
  • Data Set
    • /Hydjet_Quenched_MinBias_2760GeV/Spring10-MC_36Y_V7A-v1/GEN-SIM-RECO

Plan

  • Draw position of Beam
    • Using GenVertex?(edm::HepMCProduct) => HepMCVx?, HepMCVy? and HepMCVz?
    • Using hiSelectedVertex(reco::VertexCollection) => RecoVx?, RecoVy? and RecoVz?
  • Draw difference of HepMC? and Reco
    • HepMC? - Reco
  • Draw primary vertex resolution
    • Fit the difference by each impact parameter (each bin, 0-4,4-7,7-9,9-11,11-13,13-15,15-20) for x, y and z

Result

  • 05 July - take 7585 events of total data(200K event)
    • Primary vertex of HepMC?
