Prospects for Bd,Bs --> h+h- measurements at LHCb

Abstract

LHCb will collect large samples of Bd and Bs decays. Combining the CP-violating observables of the decays Bd-->pi+pi- and Bs-->K+K- it is possible to extract the gamma angle of the unitarity triangle. The selection of these decays within the current LHCb simulation framework is outlined and the expected annual event yields and background-to-signal ratios are quoted. Then, the results of a study on the sensitivity that LHCb can achieve for the corresponding CP-violating observables are presented.
