Muon ID Z to mumu p20 Data Sample
This first p20 sample consists of ~24 000 events. About 14k are well reconstructed Z->mumu events.
These are raw data, pick-evented following this event-list.
If handeld properly, the sample is free of bias to
be used for: - tracking efficiency studies,
- muonid efficiency studies,
- isolation efficiency studies,
- trigger studies (at L1, L2, L3).
The event list was obtained as follows:
- wzreco+muo_cert (CVS tag v05-00-01/v05-00-01) selection on unskimmed p20.04.01 TMB with RCP dedicated to skimming the data
- This was followed by wzreco+muo_cert (CVS tag v05-00-04/v05-00-04) selection with standard tag and probe RCP for early RunIIb
Be aware that using looser cuts or looser trigger requirements than what is in the RCP could yield to efficiency biases.
wzreco+muo_cert aim at selecting Z->mumu candidate following tag and probe methods.
The selected events are either:
- Zmumu events (mu1+track1, mu2+track2). By requiring isolation on mu1+track1, the mu2+track2 system can be used to study isolation efficiency.
- (mu1+track1, mu2) and dimuon trigger requirement to compute either tracking efficiency or track_trigger efficiency for mu2.
- (mu1+track1+single muon trigger,track2)
to compute either muonid efficiency or muon trigger efficiency or track trigger efficiency for mu2.
