We search for new charmless decays of neutral b hadrons to pairs of charged hadrons, using 1 fb(-1) of data collected by the CDF II detector at the Fermilab Tevatron. We report the first observation of the Bs0-->K-pi+ decay and measure B(Bs0-->K-pi+)=(5.0+/-0.7(stat)+/-0.8(syst))x10(-6). We also report the first observation of charmless b-baryon decays, and measure B(Lambdab0-->ppi-)=(3.5+/-0.6(stat)+/-0.9(syst))x10(-6) and B(Lambdab0-->pK-)=(5.6+/-0.8(stat)+/-1.5(syst))x10(-6). No evidence is found for other modes, and we set the limit B(Bs0-->pi+pi;-)<1.2x10(-6) at 90% C.L.
我们利用费米实验室Tevatron的CDF II探测器收集的1 fb⁻¹数据，寻找中性B重子到带电重子对的新的无粲衰变。我们报告了Bs0→K⁻π⁺衰变的首次观测，并测量出B(Bs0→K⁻π⁺) = (5.0±0.7(统计)±0.8(系统))×10⁻⁶。我们还报告了无粲b重子衰变的首次观测，并测量出B(Λb0→π⁻p) = (3.5±0.6(统计)±0.9(系统))×10⁻⁶以及B(Λb0→K⁻p) = (5.6±0.8(统计)±1.5(系统))×10⁻⁶。未发现其他模式的证据，我们在90%置信水平下设定极限B(Bs0→π⁺π⁻) < 1.2×10⁻⁶。
