摘要：

The CLEO Collaboration has now observed the decays B+ --> omega pi(+) and B --> omega K+ with branching ratios of (1.1(-0.5)(+0.6) +/- 0.2) x 10(-5) and (1.5(-0.6)(+0.7) +/- 0.3) x 10(-5), respectively. These are the first reported decays to charmless final states involving a vector (V) and a pseudoscalar (P) meson. The implications of these decays for others of B mesons to charmless VP final states are explored. In a model-independent approach, using only flavor SU(3) symmetry, several tests are proposed for an anticipated hierarchy among different contributions to decay amplitudes.
