Título: | Observation of B meson decays to omega K* and improved measurements for omega rho and omega f(0) |
Autor: | Babar Collaboration; Azzolini, Virginia; López-March, Neus CSIC; Martínez-Vidal, Fernando CSIC ORCID; Milanés, Diego A. CSIC ORCID; Oyanguren, Arantza CSIC ORCID; Aubert, B. | Fecha de publicación: | 20-mar-2009 | Editor: | American Physical Society | Citación: | Physical Review - Section D - Particles and Fields 79 (5): 052005 (2009) | Resumen: | We present measurements of B meson decays to the final states omega K*, omega rho, and omega f(0), where K* indicates a spin 0, 1, or 2 strange meson. The data sample corresponds to 465 x 10(6) B (B) over bar 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). | Versión del editor: | http://dx.doi.org/ 10.1103/PhysRevD.79.052005 | URI: | http://hdl.handle.net/10261/21978 | DOI: | 10.1103/PhysRevD.79.052005 | ISSN: | 1550-7998 |
