Abstract
Measurements are presented of the branching fractions of the decays B[0 over S]  → D[∓ over S]K[superscript ∓] and B[superscript 0] → D[− over S]K[superscript +] relative to the decays B[0 over S] → D[− over S]π[superscript +] and B[superscript 0] → D[superscript −]π[superscript +], respectively. The data used correspond to an integrated luminosity of 3.0 fb[superscript −1] of proton-proton collisions. The ratios of branching fractions are [B(B[0 over s] → D[∓ over s]K[superscript ∓]) over B(B[0 over s] → D[− over s]π[superscript +])] = 0.0752 ± 0.0015 ± 0.0019 and [B(B[superscript 0] → D[− over s]K[superscript +]) over B(B[superscript 0] → D[superscript −]π[superscript +])] = 0.0129 ± 0.0005 ± 0.0008, where the uncertainties are statistical and systematic, respectively.
