Abstract

The relative abundance of the three decay modes B0 -> D- K+, B0 -> D- pi+, and Bs0 -> Ds- pi+ produced in 7 TeV pp collisions at the LHC is determined from data corresponding to an integrated luminosity of 35 pb^-1. The branching fraction of B0 -> D- K+ is found to be B(B0 -> D- K+) = (2.01+-0.18stat+- 0.14syst ) 10^-4 . The ratio of fragmentation fractions f_s /f_d is determined through the relative abundance of Bs0 -> Ds- pi+ to B0 -> D- K+ and B0 -> D- pi+, leading to f_s / f_d = 0.253 +-0.017 +-0.017 +-0.020, where the uncertainties are statistical, systematic, and theoretical, respectively.
