| Title: | Measurement of the B+ -> omega l(+) v and B+ -> eta l(+) v branching fractions |
Authors: | Babar Collaboration; Azzolini, Virginia; López-March, Neus CSIC; Martínez-Vidal, Fernando CSIC ORCID; Milanés, Diego A. CSIC; Oyanguren, Arantza CSIC ORCID; Aubert, B. | Issue Date: | 25-Mar-2009 | Publisher: | American Physical Society | Citation: | Physical Review - Section D - Particles and Fields 79 (5): 052011 (2009) | Abstract: | We present a study of the charmless semileptonic B-meson decays B+ -> omega l(+) v and B+ -> eta l(+) v. The analysis is based on 3.83 x 10(8) B (B) over bar B pairs recorded at the Gamma(4S) resonance with the BABAR detector. The omega mesons are reconstructed in the channel omega -> pi(+)pi(-)pi(0) and the eta mesons in the channels eta -> pi(+)pi(-)pi(0) and eta -> gamma gamma. We measure the branching fractions B(B+ -> omega l(+) v) = (1.14 +/- 0.16(stat) +/- 0.08(syst)) x 10(-4) and B(B+ -> eta l(+) v) = (0.31 +/- 0.06(stat) +/- 0.08(syst)) x 10(-4). | Publisher version (URL): | http://dx.doi.org/ 10.1103/PhysRevD.79.052011 | URI: | http://hdl.handle.net/10261/22040 | DOI: | 10.1103/PhysRevD.79.052011 | ISSN: | 1550-7998 |
