【 摘 要 】

The LHCb experiment is a general purpose forward spectrometer operating at the Large Hadron Collider, optimized for the study of B and D hadrons. LHCb collected ∼1 fb-1of integrated luminosity during 2011 data taking, which provides an unprecedentedly large sample of B hadron decays to final states involving charmed hadrons. These decays offer many complementary ways to measure the angle γ of the CKM triangle. We present a selection of new world-leading measurements of CP-violating observables in these decays, using both time-independent and, for the first time, time-dependent analyses. A first LHCb combination of the time-independent measurements to provide a value of γ is also presented.
