We report the results of a study of two-body B meson decays to the complete set of Kπ, ππ, and KK̄ final states. The study is performed on a data sample of 31.7±0.3 million BB̄ events recorded on the Y(4S) resonance by the Belle experiment at KEKB. We observe significant signals in all Kπ final states and in the π +π - and π +π 0 final states. We set limits on the π 0 π 0 and KK̄ final states. A search is performed for partial-rate asymmetries between conjugate states for flavor-specific final states. © 2002 The American Physical Society.
