B Decays to Charmless VP Final States

Abstract

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