Abstract: (arXiv)

We report the measurement of the branching fraction and

CP

asymmetry for the

\bar{B}^{0}(B^{0})\to K^{0}_{S}K^{\mp}\pi^{\pm}

decay. The analysis is performed 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

(3.60\pm0.33\pm0.15)\times10^{-6}

and an

\mathcal{A}_{CP}

of

(-8.5\pm8.9\pm0.2)\%

, where the first uncertainties are statistical and the second are systematic. Hints of peaking structures are also observed in the differential branching fraction as functions of Dalitz variables.
