Abstract
We describe searches for B meson decays to the charmless vector-vector final states omegaK(*) and omegarho in 89x10(6) B (B) over bar pairs produced in e(+)e(-) annihilation at roots=10.58 GeV. We measure the following branching fractions in units of 10(-6): B(B-0-->omegaK(*0))=3.4(-1.6)(+1.8)+/-0.4(<6.0), B(B+-->omegaK(*+))=3.5(-2.0)(+2.5)+/-0.7(<7.4), B(B-0-->omegarho(0))=0.6(-1.1)(+1.3)+/-0.4(<3.3), and B(B+-->omegarho(+))=12.6(-3.3)(+3.7)+/-1.6. The first error quoted is statistical, the second systematic, and the upper limits are defined at 90% confidence level. For B+-->omegarho(+) we also measure the longitudinal spin alignment fraction f(L)=0.88(-0.15)(+0.12)+/-0.03 and charge asymmetry A(ch)=(5+/-26+/-2)%.
