Branching Fractions and CP Asymmetries in Two-Body Nonleptonic Charmless b-Hadron Decays

Abstract

Relative branching fractions of B^0_d,s -> h^+ h^'- decays (where h, h' = K or pi) and the direct CP asymmetry A_CP in the B^0_d -> K^+ pi^- mode are measured with 179 +- 11 pb^-1 of data collected at sqrt{s} = 1.96 TeV using the CDF II detector at the Fermilab Tevatron ppbar collider. The first branching-fraction measurement of a B^0_s meson to two pseudoscalars, Br(B^0_s -> K^+ K^-), and a search for the baryon mode Lambda^0_b -> p^+ h^- are also presented, in addition to branching-fraction limits on the rare channels B^0_s -> K^+ pi^-, B^0_d -> K^+ K^-, and B^0_s -> pi^+ pi^-.
