Fecha de publicación: | 30-jul-2007 | Editor: | American Physical Society | Citación: | Physical Review Letters 99(5): 051801 (2007) | Resumen: | We have performed a search for the flavor-changing neutral-current decays B -> πl(+)l(-), where l(+)l(-) is either e(+)e(-) or μ(+)μ(-), using a sample of 230x10(6) Υ(4S)-->B[overline B] decays collected with the BABAR detector. We observe no evidence of a signal and measure the upper limit on the isospin-averaged branching fraction to be B(B -> πl(+)l(-)) < 9.1 x 10(-8) at 90% confidence level. We also search for the lepton-flavor-violating decays B-->πe(±)mu(±) and measure an upper limit on the isospin-averaged branching fraction of B(B-->πe(±)mu(±)) < 9.2 x 10(-8) at 90% confidence level. | Descripción: | 7 pages, 1 figure, 2 tables.-- PACS nrs.: 13.20.He.-- ISI Article Identifier: 000248597500008.-- et al.(BABAR Collaboration).-- ArXiv pre-print available at: http://arxiv.org/abs/hep-ex/0703018 | Versión del editor: | http://dx.doi.org/10.1103/PhysRevLett.99.051801 | URI: | http://hdl.handle.net/10261/9895 | DOI: | 10.1103/PhysRevLett.99.051801 | ISSN: | 0031-9007 |
