Studies of charmed hadronic B decays with early LHCb data and prospects for gamma measurements

Abstract

We present the first studies of decays of the type B → DX, where D represents a charmed meson (D 0 , D ( * )+ or D s ) from the LHCb experiment at CERN. Our studies use data accumulated during the first months of the 2010 run of the LHC. This work represents the first steps on a programme towards a precision measurement of the angle γ of the CKM Unitarity Triangle. The prospects for this γ measurement are reviewed.

LHCb status and highlights

“…The data sample of ∼180 nb −1 accumulated by the time of ICHEP 2010 was sufficient to observe significant signal peaks in a large fraction of the key decay modes of the LHCb physics programme [10,11,12,13,14]. Hadronic decay modes of B mesons with branching ratios of ∼ 10 −5 have been observed.…”
