Observation of decays B-0 -> D-s((*)+)pi(-) and B-0 -> Ds(*)-K+

Observation of decays B-0 -> D-s((*)+)pi(-) and B-0 -> Ds(*)-K+

We report the observation of decays B0→Ds(*)+π- and B0→Ds(*)-K+ in a sample of 230×106 Υ(4S)→BB̄ events recorded with the BABAR detector at the SLAC PEP-II asymmetric-energy e+e- storage ring. We measure the branching fractions B(B0→Ds+π-)=(1. 3±0.3(stat)±0.2(syst))×10-5, B(B0→Ds-K+)=(2.5±0. 4(stat)...
