We present measurements of B meson decays to the final states [omega]K*, [omega][rho], and [omega]f0, where K* indicates a spin 0, 1, or 2 strange meson. The data sample corresponds to 465 x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II ee− collider at SLAC. B meson decays involving vector-scalar, vector-vector, and vector-tensor final states are analyzed; the latter two shed new light on the polarization of these final states. We measure the branching fractions for nine of these decays; five are observed for the first time. For most decays we also measure the charge asymmetry and, where relevant, the longitudinal polarization f{sub L}.

The authors describe searches for B meson decays to the charmless vector-vector final states {omega}K*, {omega}p, {omega}{omega}, and {omega}{phi} with 233 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation at {radical}s = 10.58 GeV. They also search for the vector-scalar B decay to {omega}f{sub 0}.

The authors present preliminary measurements of B meson decays to B 2![omega][pi], B+ 2![omega]K+, and B° 2![omega]K°. The data were recorded with the BABAR detector and correspond to 88.9 x 106 B{bar B} pairs produced in e+e− annihilation at the [Upsilon](4S) resonance. They find statistically significant signals for all three channels: [Beta](B+ 2![omega][pi]+) = (5.4 ± 1.0 ± 0.5) x 10−6, [Beta](B+ 2![omega]K+) = (5.0 ± 1.0 ± 0.4) x 10−6, and [Beta](B° 2![omega]K°) = (5.3{sub -1.2}{sup +1.4} ± 0.5) x 10−6. They also measure time-integrated charge asymmetries [Alpha]{sub ch}(B+ 2![omega][pi]+) = 0.04 ± 0.17 ± 0.01 and [Alpha]{sub ch}(B+ 2![omega]K+) = -0.05 ± 0.16 ± 0.01.
