摘要：
We consider two body decays of B meson into a light vector (V) and a pseudoscalar (P) meson. The constraint obtained from the B --> PP modes on the parameter space of the input parameters is imposed also on B --> VP modes. In particular we constrain xi=(1/N-c) for those modes from recently measured B --> omega K, phi K and are able to get a satisfactory pictures for all modes where data exists. Modes that should be seen shortly and those with possibly large CP asymmetries are identified. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
