July 1998. 81(2) : 272-276http://publish.aps.org/https://hdl.handle.net/1808/1365We have searched for two-body charmless decays of B mesons to purely hadronic exclusive final states including omega or phi mesons using data collected with the CLEO II detector. With this sample of 6.6 x 10(6) B mesons we observe a signal for the omega K+ final state, and measure a branching fraction of B(B+ --> omega K+) = (1.51(-0.6)(+0.7) +/- 0.2) X 10(-5). We also observe some evidence for the phi K* 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. [S0031-9007(98)06568-5].en-USArticleopenAccess
