Installation

3_7_0_patch2

  • Create your local area:
    cmsrel CMSSW_3_7_0_patch2
    cd CMSSW_3_7_0_patch2/src
    cmsenv
    
  • Common analysis packages
    cvs co -r  Colin_37X_June18 -d   AnalysisDataFormats/PFAnalyses UserCode/PFAnalyses/AnalysisDataFormats/PFAnalyses      
    cvs co -r  Artur_37X_June18_branch -d   PFAnalyses/CommonTools   UserCode/PFAnalyses/CommonTools

  • Particle flow reconstruction: the default particle flow in 3_7_0_patch2 is close to perfect. no need to install a specific version of the particle flow in your local area.
  • Common tools with bug fix of string parser
    cvs co -r V00-02-16 CommonTools/Utils
    
  • KoPFA
    cvs co -d KoPFA UserCode/KoPFA
    scram b -j 4
    

  • L1 muon Selection Cut
    • pt > 15 GeV, |η| < 2.1
    • Number of pixel hits > 0, Number of hits in the tracker > 10
    • Transverse impact parameter of the muon with respect to the beam spot |dxy| < 2 mm
    • Chi2 / ndof of the global muon fit < 10
    • Number of valid hits in the muon chambers used in the global muon fit > 0
    • Relative combined isolation=(sumPt+emEt+hcalEt)/(muon pt) < 0.15 in a deltaR < 0.3 cone
  • Z to mumu Selection Cut
    • di-muon pairs made by opposite-charge muons and with invariant mass 60 < m < 120 GeV/c
    • acceptance cuts
      • both muons must have |pt| > 20 GeV
      • at least one of the muons must be within |η| < 2.1 for triggering, the remaining muon must be within |η| < 2.4
      • both muons must be indentified as Global Muons and must have > 10 total (pixel+strips) hits in the Tracker detector
