Determination of the branching fractions of B0s→D∓sK± and B0→D−sK+

Abstract : Measurements are presented of the branching fractions of the decays B0s→D∓sK± and B0→D−sK+ relative to the decays B0s→D−sπ+ and B0→D−π+, respectively. The data used correspond to an integrated luminosity of 3.0 fb−1 of proton-proton collisions. The ratios of branching fractions are B(B0s→D∓sK±)B(B0s→D−sπ+)=0.0752±0.0015±0.0019 and B(B0→D−sK+)B(B0→D−π+)=0.0129±0.0005±0.0008, where the uncertainties are statistical and systematic, respectively.
