2010 Heavy Ion Trigger Study for Z0 in November data
How to run HLT
scramv1 p -n cms370 CMSSW CMSSW_3_7_0
cd cms370/src
cvs co -r CMSSW_3_7_0 HLTrigger/Configuration
cd HLTrigger/Configuration/test
(put your input files(should be RAW) on the OnLine_HLT_HIon.py)

L1 Rate Problems
Z0 Express Stream
- 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?
- 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
