Measurement of the CKM angle γ at LHCb

Abstract

The CKM angle γ is the least well known angle of the unitarity triangle, and the only one easily accessible at tree level. The ultimate goal of degree level precision requires exploitation of all possible channels and techniques. Presented here are some of the latest results on the CKM angle γ from the LHCb experiment. Included are measurements of CP violation using the B ± → DK ± decays and a variety of different D decay modes, and a measurement γ from B 0 → DK * 0 where the D decays to either K 0 s π + π − or K 0 s K + K − . A combination of these and other γ-related measurements is also presented.
