Título: | Model-independent search for the decay B+-> l(+)nu(l)gamma |
Autor: | Azzolini, Virginia; López-March, Neus CSIC; Martínez-Vidal, Fernando CSIC ORCID; Milanés, Diego A. CSIC ORCID; Oyanguren, Arantza CSIC ORCID; Babar Collaboration; Aubert, B. | Fecha de publicación: | 17-dic-2009 | Editor: | American Physical Society | Citación: | Physical Review - Section D - Particles and Fields 80 (11): 111105 (2009) | Resumen: | We present a search for the radiative leptonic decay B+ -> l+ nu gamma, where l=e,mu, using a data sample of 465 million B-meson pairs collected by the BABAR experiment. In this analysis, we fully reconstruct the hadronic decay of one of the B mesons in Upsilon(4S) -> B+B- decays, then search for evidence of B+ -> l+ nu gamma in the rest of the event. We observe no significant evidence of signal decays and report model-independent branching fraction upper limits of BR(B+ -> e+ nu gamma)<17e-6, BR(B+ -> mu+ nu gamma)< 24e-6, and BR(B+ -> l+ nu gamma)<15.6e-6 (l= e or mu), all at the 90% confidence level. | Versión del editor: | http://dx.doi.org/ 10.1103/PhysRevD.80.111105 | URI: | http://hdl.handle.net/10261/21938 | DOI: | 10.1103/PhysRevD.80.111105 | ISSN: | 1550-7998 |
