2010 Heavy Ion Trigger Study for Z0 in November data

Z0 Express Stream

  1. Motivation
    • In the latest CMSSW version such as 3_8_X and 3_9_X, there is no high object muon trigger, but only L1_DoubleMuOpen, called HLT_L1DoubleMuOpen. This study started to check if this is really what we want or we need another trigger path?
  2. Candidates for Z0 Express Stream
    • L1_DoubleMuOpen : more than 2 muons with any pt in the Level 1 : current default dilepton trigger
    • L2_SingleMu0 : more than 1 muon with no pt in the Level 2
    • L2_DoubleMu0 : more than 2 muons with no pt in the Level 2
    • L2_Mu3 : more than 1 muon with pt 3 GeV/c in the Level 2
    • L2_Mu5 : more than 1 muon with pt 5 GeV/c in the Level 2
    • L2_Mu7 : more than 1 muon with pt 7 GeV/c in the Level 2
    • L2_Mu10 : more than 1 muon with pt 10 GeV/c in the Level 2
    • L2_Mu12 : more than 1 muon with pt 12 GeV/c in the Level 2

Data Sample
  • Merged sample with HLT-RECO in the 370 (13k events) : /castor/cern.ch/user/d/dmoon/cms370/Hydjet_MinBias_2.76TeV_Z0_Flat_Emb_Reco/Merge
  • Generated information : link
  • Muon pt of Z0

Trigger Performace
  1. Acceptance
