We report on a search for charmless hadronic B decays to the three-body final states K(0)(S)h(+)pi(-), K(+)h(-)pi(0), K(0)(S)h(+)pi(0) (h(+/-) denotes a charged pion or kaon), and their charge conjugates, using 13.5 fb(-1) of integrated luminosity produced near sqrt[s]=10.6 GeV, and collected with the CLEO detector. We observe the decay B-->K0pi(+)pi(-) with a branching fraction (50(+10)(-9)(stat.)+/-7(syst.))x10(-6) and the decay B-->K(*+)(892)pi(-) with a branching fraction (16(+6)(-5)(stat.)+/-2(syst.))x10(-6).
我们报告了一项利用在质心能量(\sqrt{s}=10.6) GeV附近产生的(13.5) fb(^{-1})的积分亮度，并通过CLEO探测器收集的数据，对无粲强子(B)衰变到三体末态(K_{S}^{0}h^{+}\pi^{-})、(K^{+}h^{-}\pi^{0})、(K_{S}^{0}h^{+}\pi^{0})（(h^{+/-})表示带电的 pion 或 kaon）及其电荷共轭态进行的搜索。我们观测到衰变(B\to K_{0}\pi^{+}\pi^{-})，其分支比为((50(^{+10}{-9})(stat.)\pm7(syst.))\times10^{-6})，以及衰变(B\to K^{(* +)}(892)\pi^{-})，其分支比为((16(^{+6}{-5})(stat.)\pm2(syst.))\times10^{-6})。
