Abstract

We describe searches for B meson decays to the charmless vector-vector final states ωK* and ωρ in 89 × 10 BB̄ pairs produced in e e annihilation at √s = 10.58 GeV. We measure the following branching fractions in units of 10 : B(B → ωK* ) = 3.4 ± 0.4(<6.0), B(B → ωK* ) = 3.5 ± 0.7(<7.4), B(B → ωρ ) = 0.6 ± 0.4(<3.3), and B(B → ωρ ) = 12.6 ± 1.6. The first error quoted is statistical, the second systematic, and the upper limits are defined at 90% confidence level. For B → ωρ we also measure the longitudinal spin alignment fraction f = 0.88 ± 0.03 and charge asymmetry A = (5 ± 26 ± 2)%. © 2005 The American Physical Society. 6 + - -6 0 0 +1.8 + + +2.5 0 0 +1.3 + + +3.7 + + +0.1..
