Description

The identification of jets containing the weak decay of a B-hadron is an essential tool for a wide range of analyses in the context of the Standard Model and beyond. A variety of algorithms exploit the long lifetime and the presence of soft leptons to discriminate these jets from those associated to light quarks. The distributions of the corresponding observables - track impact parameters, secondary vertices and lepton momenta - were measured in pp collisions at sqrt(s) = 7 TeV and compare well to the predictions of Monte Carlo simulation. First results on efficiencies and mis-identification rates are shown.
