摘要：

The theory of CP violation based on phases in weak couplings in the Cabibbo-Kobayashi-Maskawa matrix requires the phase gamma = ArgV(ub)* (in a standard convention) to be nonzero. A measurement of gamma is proposed based on charged B meson decay rates to pi+K0, pi0K+, pi+pi0, and the charge-conjugate states. The corresponding branching ratios are expected to be of the order of 10(-5).
