Study of $B$-meson decays to an $\omega$ meson and a light vector meson

We present measurements of branching fractions, polarization, and $CP$-violation charge asymmetries for $B$-meson decays to two- body final states containing an $\omega$ meson and a low-mass $\pi\pi$ or $K\pi$ system. The analysis was performed on a data sample consisting of 465$\times10^{-6}$ $B\kern 0.18em\overline {\kern -0.18em B}$ pairs collected with the {\sl B{\scriptsize A} B{\scriptsize AR}} detector at the PEP-II asymmetric-energy $B$ Factory at SLAC. We obtain improved measurements for the previously observed decay $B\rightarrow\omega\rho^+$, and evidence or observation of new modes with $\omega$ and $K^*(892) $, $K^*_0(1430)$, and $K^*_2(1430)$.
