Abstract

We describe searches for B meson decays to the charmless vector-vector final states omega K-{*}, omega rho, omega omega, and omega phi with 233x10(6) B (B) over bar pairs produced in e(+)e(-) B (B) over bar annihilation at root s =10.58 GeV. We also search for the vector-scalar B decay to omega f(0). We measure the following branching fractions in units of 10(-6): B(B-0 ->omega K-{*}0)=2.4 +/- 1.1 +/- 0.7 (< 4.2), B(B+->omega K{*}+)=0.6(-1.2-0.9)(+1.4+1.1) (< 3.4), B(B-0 ->omega rho(0))=-0.6 +/- 0.7(-0.3)(+0.8) (< 1.5), B(B+->omega rho(+))=10.6 +/- 2.1(-1.0)(+1.6), B(B-0 ->omega omega)=1.8(-0.9)(+1.3)+/- 0.4 (< 4.0), B(B-0 ->omega phi)=0.1 +/- 0.5 +/- 0.1 (< 1.2), and B(B-0 ->omega f(0))=0.9 +/- 0.4(-0.1)(+0.2) (< 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+->omega rho(+) decays we also measure the longitudinal spin component f(L)=0.82 +/- 0.11 +/- 0.02 and the charge asymmetry A(CP)=0.04 +/- 0.18 +/- 0.02.
