Abstract: Measurements are presented of the branching fractions of the decays BS 0 → DS ∓K∓ and B0 → DS −K+ relative to the decays BS 0 → DS −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 (Formula presented.) where the uncertainties are statistical and systematic, respectively.[Figure not available: see fulltext.]
