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?

• • Primary vertex of Reco

• • Difference between HepMC? and Reco

• • Primary vertex resolution
