摘要：

We report the results of a study of two-body B meson decays to the complete set of Kpi, pipi, and K (K) over bar final states. The study is performed on a data sample of 31.7+/-0.3 million B (B) over bar events recorded on the Y(4S) resonance by the Belle experiment at KEKB. We observe significant signals in all Kpi final states and in the pi(+)pi(-) and pi(+)pi(0) final states. We set limits on the pi(0)pi(0) and K (K) over bar final states. A search is performed for partial-rate asymmetries between conjugate states for flavor-specific final states.
