【 摘 要 】

With a sample of approximately 89 million BB pairs collected with the BABAR detector, we measure branching fractions, determine the degree of longitudinal polarization, and search for direct CP violation in the decays B0 yields thetaK(Sup asterisk 0) and B+ yields thetaK(sup asterisk +). We perform a search for other charmless vector-vector B decays involving p and Kasterisk(892) resonances and observe the decays B+ yields p(sup 0)K(sup asterisk +) and B+ yields p(sup 0)p(sup +).
