Abstract

The CLEO Collaboration has now observed the decays B+ωπ+B^+ \to \omega \pi^+ and BωK+B \to \omega K^+ with branching ratios of (1.10.5+0.6±0.2)×105(1.1^{+0.6}_{-0.5} \pm 0.2) \times 10^{-5} and (1.50.6+0.7±0.3)×105(1.5^{+0.7}_{-0.6} \pm 0.3) \times 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.
