摘要：
Relative branching fractions of B-d,B-s -> h(+)h'- decays (where h, h' = K or pi) and direct CP asymmetry in B-d -> K+ pi(-) have been measured with 180 pb(-1) of data collected by the CDFII detector at the Tevatron collider. This includes the first BR measurement of a charmless Bs -> PP decay (B-s -> K+K-).
