Measurement of branching fraction and final-state asymmetry for the $bar{B}^{0}to K^{0}_{S}K^{mp}pi^{pm}$ decay

We report a measurement of the branching fraction and final-state asymmetry for the $bar{B}^{0}to K^{0}_{S}K^{mp}pi^{pm}$ decays. The analysis is based on a data sample of 711 $rm{fb}^{-1}$ collected at the $Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. We obtain a branching fraction of $(3.60pm0.33pm0.15)times10^{-6}$ and a final-state asymmetry of $(-8.5pm8.9pm0.2)%$, where the first uncertainties are statistical and the second are systematic. Hints of peaking structures are seen in the differential branching fractions measured as functions of Dalitz variables.
