Bdecays to charmlessVPfinal states

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