Abstract

We report a measurement of the exclusive B+ meson decay to the Ds(*)-K+π+ final state using 657×106BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We use Ds*-→Ds-γ and the Ds-→ π-, K̄*(892)0K- and KS0K- decay modes for Ds(*) reconstruction and measure the following branching fractions: B(B+→Ds-K+π+)=(1.71-0.07+0. 08(stat)-0.20+0.20(syst)±0.15(Bint))×10-4 and B(B+→Ds*- K+π+)=(1.31-0.12+0.13(stat)-0.25+0.25(syst)±0.12(Bint))×10-4. The uncertainties are due to statistics, experimental systematic errors, and uncertainties of intermediate branching fractions, respectively.
