Measurement of the branching fractions of Bs0->Ds K, Bs0->Ds Pi and B0->Ds K

Abstract

The relative branching fraction of the decay Bs0->Ds K with respect to Bs0 -> Ds Pi is determined from pp collision data collected with the LHCb experiment and corresponding to an integrated luminosity of 3 fb-1. From the same data, the branching fractions of Bs0 -> Ds Pi and B0 -> Ds K are extracted with respect to B0 -> D Pi. The obtained values for the Bs0->Ds K and B0 -> Ds K branching fractions are more precise than the existing world average values.
