Abstract
Measurements are presented of the branching fractions of the decays B 0S → D ∓S K ∓ and B 0 → D −S K + relative to the decays B 0S → D −S π + and B 0 → 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.
