– 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
