1. Samples used
MC W+Jets: /WJets-madgraph/Spring10-START3X_V26_S09-v1/GEN-SIM-RECO 1e+07 events
MC QCD:
Data jet-Triggered (Run: 141956-144114 ): /JetMET/Run2010A-Sep17ReReco_v2/RECO
2. Selections and imposed cuts
For Muons:
For Electron:
For Tracks:
For Jets:
3. Definitions of numerator and denominator for FR
Numerator:
Denominator:
some details for W+Jets sample: As it was mentioned above, W->mu and track associated with it are removed from numerator and denominator respectively. This is done in the following way.
4. Meaning of FR
Knowing the FR as it is defined above, we can find what is the probability that a track gives us a muon (under muon, it is meant all muons coming from QCD part, includes decays-in-flight, punchthrough etc). This method will be used for SUSY analysis to estimate W+Jets background, which is second most important bkc after TTbar. The control sample for that method is jet triggered data ( /JetMET/Run2010A-Sep17ReReco_v2/RECO )
More updates coming.
