How many muons should the muon detectors see ?

2000 events b=0
  • I have counted the muons (with status=1) in the right pt and rapidity range for the DT and CSC.
  1. DT
    • pt>4GeV/c && |eta|<1.2
    • number of muons seen by the DT: 50 muons
  2. CSC
    • pt>3GeV/c && -2.4<eta<-0.8 && 0.8<eta<2.4
    • number of muons seen by the CSC: 100 muons

  • Comment:

When embedding quarkonia into hydjet, the decayed muons have a pt spectra peaked almost at 2GeV/c, and droping less fast that those from the hydjet events. This is why one sees more muons in the muons detectors with those samples.

With right cut: cutting on p instead of pt:

  • p>4Gev/c && |eta|<1.2: number of muons seen by the DT 110 muons
  • number of muons that have p>5 GeV/c, and therefore can be reconstructed as STA muons in the DT = 55
  • p>3GeV/c && -2.4<eta<-0.8 && 0.8<eta<2.4 : number of muons seen by the CSC 1012 muons
