摘要：

In view of recent experimental progress in rate and CP asymmetry measurements in B+/- --> DK+/- we reconsider information on the weak phase gamma which can be obtained from these processes. Model-independent inequalities are proven for sin(2) gamma in terms of two ratios of partial rates for B+/-.0 --> DXs+/-.0 where X-s is any multiparticle charmless state carrying strangeness +/-1. Good prospects are shown to exist for using these inequalities and CP asymmetry measurements in two body and multibody decays in order to improve present bounds on gamma.
