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 ×10 B mesons we observe a signal for the ωK+ final state, and measure a branching fraction of B(B →ωK )=(1.5 )±0.2)×10 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. © 1998 American Physical Society. 6 + + +0.7 −5 −0.6
