Abstract

Measurements are presented of the branching fractions of the decays B0 s → D∓ s K∓ and B0 → D− s K+ relative to the decays B0 s → D− s π + 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(B0 s → D∓ s K∓) B(B0 s → D − s π+) = 0.0752 ± 0.0015 ± 0.0019 and B(B0 → D− s K+) B(B0 → D−π+) = 0.0129 ± 0.0005 ± 0.0008, where the uncertainties are statistical and systematic, respectively
