| dc.description | We report a measurement of the exclusive $B^+$ meson decay to the final state $D_s^- K^+π^+$ using $520 \times 10^{6} B\bar{B}$ pairs collected near the $Υ(4S)$ resonance, with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. Using the $D_S^- \to ϕπ^-$ decay mode to reconstruct $D_s^-$ mesons, we obtain the branching fraction ${\cal B}(B^+\to D_s^-K^+π^+)= (1.77^{+0.12}_{-0.12} {\mathrm (stat)} \pm 0.16 {\mathrm (syst)} \pm 0.23 {\cal(B)})\times 10^{-4}$. We also present preliminary results of a study of the two-body $D_sK$, $D_sπ$ and $Kπ$ subsystems observed in this final state. | |
