Abstract

We report improved measurements of branching fractions for B→Kπ, π⁺π^-, π⁺π⁰, and KK̄ decays based on a data sample of 85.0 million BB̄ pairs collected at the Y(45) resonance with the Belle detector at the KEKB e⁺e^- storage ring. This data sample is almost three times larger than the sample previously used. We observe clear signals for B→Kπ, π⁺ π^- and π⁺π⁰ decays and set upper limits on B→KK̄ decays. The results can be used to give model-dependent constraints on the CKM angle φ₃, as well as limits on the hadronic uncertainty in the time-dependent analysis of the angle φ₂.
