The CLEO Collaboration has now observed the decays B+→ ωπ+ and B⃗ωK+ with branching ratios of (1.1+0.6−0.5±0.2)×10−5 and (1.5+0.7−0.6±0.3)×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.
