Preliminary stuffPreliminary stuff• Summer09 ppMuMuX sample with CMSSW_3_3_2
– it requires opposite charge generated dimuons from heavy processes or K, pi, K0L decays in flight
• Muon properties:– Pt > 2.5 GeV– Eta < 2.5– Muon has a track
• Tracker + Global– “Muon has a track” does not imply is a Tracker Mu, it can be
Global Mu without beeing Tracker Mu
• Muons are defined– Prompt
• if Rxy < 4.4 cm– DiF (decays in flight)
• if Rxy > 4.4 cm

Preliminary ConclusionsPreliminary Conclusions
• Prompt and DiF muons have very different distributions
• Loose cuts retain most Prompt and DiF– e.g. DeltaR =0.05, DeltaPt =0.1
• Tight cuts reject most DiF– e.g. DeltaR =0.005, DeltaPt =0.05
