Book Description
We report measurements of direct CP-violating asymmetries in charmless decays of neutral bottom hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 1 fb−1 of integrated luminosity, we obtain the first measurements of direct CP violation in bottom strange mesons, A{sub CP}(B{sub s}° → K−?) = +0.39 ± 0.15 (stat) ± 0.08 (syst), and botton baryons, A{sub CP}(?{sub b}° → p?−) = + 0.03 ± 0.17 (stat) ± 0.05 (syst) and A{sub CP} (?{sub b}° → pK−) = +0.37 ± 0.17 (stat) ± 0.03 (syst). In addition, they measure CP violation in B° → K+?− decays with 3.5? significance, A{sub CP} (B° → K+?−) = -0.086 ± 0.023 (stat) ± 0.009 (syst), in agreement with the current world average. Measurements of branching fractions of B{sub s}° → K+K− and B° →?+?− decays are also updated.

Book Description
The authors present new CDF results on the branching fractions and time-integrated direct CP asymmetries for B{sup 0} and B{sub s}{sup 0} decay modes into pairs of charmless charged hadrons (pion or kaon). The data set for this update amounts to 1 fb{sup -1} of {bar p}p collisions at {radical}s = 1.96 TeV. They report the first observation of the B{sub s}{sup 0} {yields} K{sup -}{pi}{sup +} mode and a measurement of its branching fraction and direct CP asymmetry. They also observe for the first time two charmless decays of b-baryon: {Lambda}{sub b}{sup 0} {yields} p{pi}{sup -} and {Lambda}{sub b}{sup 0} {yields} pK{sup -}.
