TL;DR

This paper reports measurements of B meson decays to omegaK*, omegarho, and omega f_0 final states, including new observations and polarization analyses based on a large data sample from the BABAR experiment.

Contribution

It provides the first measurements of several B meson decay modes involving omega and strange mesons, with detailed polarization and charge asymmetry results.

Findings

Five decay modes observed for the first time.

Branching fractions measured for nine decay channels.

Polarization and charge asymmetry parameters analyzed.

Abstract

We present measurements of B meson decays to the final states omegaK*, omegarho, and omega f_0, where K* indicates a spin 0, 1, or 2 strange meson. The data sample corresponds to 465x10^6 BBbar pairs collected with the BABAR detector at the PEP-II e+e- 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_L.
