Branching Fractions and CP Asymmetries in Hadronic Charmless Decays of B Mesons at CDF

摘要

We present an overview of branching ratio and direct CP asymmetry measurements for charmless b-hadron decays into two-body hadronic final states using 180 pb-1 of data collected by the CDF II experiment at the Fermilab Tevatron collider. The following modes are treated: Bd,s0→h+h'1, Λb0→ph-, where h and h' stand for K or π , Bu+→ΦK+, and Bs0→ΦΦ.
