Abstract

We report the observation of the decay B⊃-→Ds(*)+K⊃- ⊃-ν̄ based on 342fb⊃-1 of data collected at the ε(4S) resonance with the BABAR detector at the PEP-II e⊃+e⊃- storage rings at SLAC. A simultaneous fit to three Ds+ decay chains is performed to extract the signal yield from measurements of the squared missing mass in the B meson decay. We observe the decay B⊃-→Ds(*)+K⊃-⊃- ν̄ with a significance greater than 5 standard deviations (including systematic uncertainties) and measure its branching fraction to be B(B⊃-→Ds(*)+K⊃-⊃-ν̄)=[6.13-1.03+1. 04(stat)±0.43(syst)±0.51(B(Ds))]×10⊃-4, where the last error reflects the limited knowledge of the Ds branching fractions.
