We report final measurements of direct C P -violating asymmetries in charmless decays of neutral bottom hadrons to pairs of charged hadrons with the upgraded Collider Detector rose at the Fermilab Tevatron. Using the complete s = 1.96 TeV proton-antiproton collisions rose data set, corresponding to 9.3 fb 1 of integrated luminosity, we measure A ( Λ b 0 p π ) = + 0.06 0.07 ( stat ) 0.03 ( syst ) and A ( Λ b 0 p K ) = 0.10 0.08 ( stat ) 0.04 ( syst ) , compatible with no asymmetry. In addition we measure the C P -violating asymmetries in B s 0 K π + and B 0 K + π decays to be A ( B s 0 K π + ) = + 0.22 0.07 ( stat ) 0.02 ( syst ) and A ( B 0 K + π ) = 0.083 0.013 ( stat ) 0.004 ( syst ) , respectively, which are significantly different from zero and consistent with current world averages.

Mass distribution of reconstructed candidates, where the charged pion mass is assigned to both tracks. The sum of the fitted distributions and the individual components (C-conjugate decay modes are also implied) of the signal and background rose is overlaid on the data distribution.

Distribution of the average value of κsum (a) and κdif (b) as a function of mπ+π-. The fit function is overlaid. For reference, the distribution of mπ+π- is shown by the dashed lower histogram. Dashed vertical lines indicate the position, from left to right, rose of the following signals: B0 K+π-, Bs0 K-π+, Λb0 pK-, Λb0 pπ-. Reuse & Permissions ×
