We report final 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 the complete s=1.96TeV proton-antiproton collisions data set, corresponding to 9.3fb-1 of integrated luminosity, we measure A(Λb0→pπ-)=+0.06±0.07(stat)±0.03(syst) and A(Λb0→pK-)=-0.10±0.08(stat)±0.04(syst), compatible with no asymmetry. In addition we measure the CP-violating asymmetries in Bs0→K-π+ and B0→K+π- decays to be A(Bs0→K-π+)=+0.22±0.07(stat)±0.02(syst) and A(B0→K+π-)=-0.083±0.013(stat)±0.004(syst), respectively, which are significantly different from zero and consistent with current world averages.
