We present measurements of B meson decays to the final states ωK*, ωρ, ; ωf0, where K* indicates a spin 0, 1, or 2 strange meson. The data sample corresponds to 465×106 BB̄ pairs collected with the BABAR detector at the PEP-II e+e- collider at SLAC. B meson decays involving vector-scalar, vector-vector, ; vector-tensor final states are analyzed; the latter two shed new light on the polarization of these final states.

Abstract
We present measurements of B meson decays to the final states ωK*, ωρ, ; ωf0, where K* indicates a spin 0, 1, or 2 strange meson. The data sample corresponds to 465×106 BB̄ pairs collected with the BABAR detector at the PEP-II e+e- collider at SLAC. B meson decays involving vector-scalar, vector-vector, ; 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 fL. © 2009 The American Physical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
