摘要：

We propose a way to extract the ratio of CKM matrix elements V(ub)/V(cb) from the measurement of the two-body non-leptonic decays B- --> D0KBAR-, B- --> D- K0BAR and B0BAR --> D0K0BAR, which are proportional to \V(ub)\2, and the decays B- --> D0K-, B0BAR --> D+K- and B0BAR --> D0K0BAR, which are proportional to \V(cb)\2, based on isospin symmetry. We also analyze the modifications of our predictions due to final state interactions, and find them to be significant.
