Abstract
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 B-s(0)-> K-pi(+) decay and measure B(B-s(0)-> 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(Lambda(0)(b)-> p pi(-))=(3.5 +/- 0.6(stat)+/- 0.9(syst))x10(-6) and B(Lambda(0)(b)-> pK(-))=(5.6 +/- 0.8(stat)+/- 1.5(syst))x10(-6). No evidence is found for other modes, and we set the limit B(B-s(0)->pi(+)pi(-))< 1.2x10(-6) at 90% C.L.
