Abstract

Using BB events recorded in the Belle detector, the charge averaged branching fractions for B→π⁺π^-, K⁺π^-, K⁺π⁰, K⁰π⁰ were measured with statistically significant signals. The results confirm that B(B⁰→K⁺π^-) is larger than B(B⁰→π⁺π^-), and indicate that B(B⁺→h⁺π⁰) and B(B⁰→K⁰π⁰) seem to be larger than expected in relation to the B⁰→h⁺π^- and B⁺→K⁰π⁺ modes based on isospin or penguin dominance arguments.
