Measurement of btagging efficiency using ttbar events
Jet flavour tagging is one of the key ingredients of the diverse physics program of the CMS experiment. Various flavour taggers based on the lifetime and semileptonic decay of the heavy quarks have been implemented. They use jets, tracks, leptons and/or vertices. We exploit the \ttbar samples collec...
