B meson decays to ωK*, ωρ, ωω, ωϕ, and ωf0
We describe searches for B meson decays to the charmless vector-vector final states ω K ∗ , ω ρ , ω ω , and ω ϕ with 233 × 10 6 B ¯¯¯ B pairs produced in e + e − B ¯¯¯ B annihilation at √ s = 10.58 GeV . We also search for the vector-scalar B decay to ω f 0 . We measure the following branching f...

We describe searches for B meson decays to the charmless vector-vector final states ω K ∗ , ω ρ , ω ω , and ω ϕ with 233 × 10 6 B ¯¯¯ B pairs produced in e + e − B ¯¯¯ B annihilation at √ s = 10.58 GeV . We also search for the vector-scalar B decay to ω f 0 . We measure the following branching fractions in units of 10 − 6 : B ( B 0 → ω K * 0 ) = 2.4 ± 1.1 ± 0.7 ( < 4.2 ) , B ( B + → ω K * + ) = 0.6 + 1.4 + 1.1 − 1.2 − 0.9 ( < 3.4 ) , B ( B 0 → ω ρ 0 ) = − 0.6 ± 0.7 + 0.8 − 0.3 ( < 1.5 ) , B ( B + → ω ρ + ) = 10.6 ± 2.1 + 1.6 − 1.0 , B ( B 0 → ω ω ) = 1.8 + 1.3 − 0.9 ± 0.4 ( < 4.0 ) , B ( B 0 → ω ϕ ) = 0.1 ± 0.5 ± 0.1 ( < 1.2 ) , and B ( B 0 → ω f 0 ) = 0.9 ± 0.4 + 0.2 − 0.1 ( < 1.5 ) .
