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)±0.4(syst))×10-5, B(B0→Ds*+π-)=(2.8±0. 6(stat)±0.5(syst))×10-5, and B(B0→Ds*-K+)=(2.0±0. 5(stat)±0.4(syst))×10-5. The significances of the measurements to differ from zero are 5, 9, 6, and 5 standard deviations, respectively. This is the first observation of B0→Ds+π-, B0→Ds*+π-, and B0→Ds*-K+ decays. © 2007 The American Physical Society
