B meson decays to omega K*, omega p, omega omega, omega phi, and omega f(0)

We describe searches for B meson decays to the charmless vector-vector final states ωK∗, ωρ, ωω, and ωϕ with 233×106 BB⎯⎯⎯ pairs produced in e+e− BB⎯⎯⎯ annihilation at s√=10.58  GeV. We also search for the vector-scalar B decay to ωf0. We measure the following branching fractions in units of 10−6: ℬ(B0→ωK*0)=2.4±1.1±0.7  (<4.2), ℬ(B+→ωK*+)=0.6+1.4+1.1−1.2−0.9  (<3.4), ℬ(B0→ωρ0)=−0.6±0.7+0.8−0.3  (<1.5), ℬ(B+→ωρ+)=10.6±2.1+1.6−1.0, ℬ(B0→ωω)=1.8+1.3−0.9±0.4  (<4.0), ℬ(B0→ωϕ)=0.1±0.5±0.1  (<1.2), and ℬ(B0→ωf0)=0.9±0.4+0.2−0.1  (<1.5). In each case the first error quoted is statistical, the second systematic, and the upper limits are defined at the 90% confidence level. For B+→ωρ+ decays we also measure the longitudinal spin component fL=0.82±0.11±0.02 and the charge asymmetry CP=0.04±0.18±0.02.
