Branching fractions and CP asymmetries in B --> h+ h'-

Abstract

Relative branching fractions of Bd,Bs --> h+ h'- decays (where h,h'= K or pi) and direct CP asymmetry in Bd --> 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 (Bs --> K+K-).
