Z'→ W⁺W^-→l⁺l^-MET

Monte Carlo study

• MC samples used in the analysis:
  

We select events with one electron and one muon, oppositely charged, requiring

• process.selectedPatMuons.cut = 'pt>20. & abs(eta)<2.4 & isPFMuon & (isGlobalMuon|isTrackerMuon) & dB<0.02 & (caloIso+trackIso)/pt<0.15'
• process.selectedPatElectrons.cut = 'pt>20. & abs(eta)<2.5 & hadronicOverEm<0.05 & (caloIso+trackIso)/pt<0.15'

The events passing the selection requirements are used to construct a transverse mass.

• Transverse mass distribution for signal and background:
  

• Significance of the signal (Z' 0.5 TeV) as a function of the invariant transverse mass:
  

• Significance of the signal (Z' 1.0 TeV) as a function of the invariant transverse mass:
  

• Significance of the signal (Z' 1.5 TeV) as a function of the invariant transverse mass:
  

• Significance of the signal (Z' 2.0 TeV) as a function of the invariant transverse mass:
  

• Event yield after (right) and before (left) applying the cut in the invariant transverse mass:
  

• Event yield after (right) and before (left) applying the cut in the invariant transverse mass:
  

• Event yield after (right) and before (left) applying the cut in the invariant transverse mass:
  

• Event yield after (right) and before (left) applying the cut in the invariant transverse mass:
  

• Expected 95% CL upper limit on the cross section:
  

• Efficiency (basic selection X efficiency of the M-T cut) as a function of the Z' mass:
