Abstract

We have searched for two-body charmless decays of B mesons to purely hadronic exclusive final states including ω or φ mesons using data collected with the CLEO II detector. With this sample of 6.6 X 10⁶ B mesons we observe a signal for the ωK⁺ final state, and measure a branching fraction of Ɓ(B⁺→ωK⁺) = (1.5_-0.6^+0.7 ± 0.2) X 10^-5. We also observe some evidence for the φK* final state, and upper limits are given for 22 other decay modes. These results provide the opportunity for studies of theoretical models and physical parameters.
