CSIC ORCID | Fecha de publicación: | nov-2011 | Editor: | American Physical Society | Citación: | Physical Review Letters 107(19): 191801 (2011) | Resumen: | A search has been performed for Bs0→μ+μ- and B0→μ+μ- decays using 7 fb-1 of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron collider. The observed number of B0 candidates is consistent with background-only expectations and yields an upper limit on the branching fraction of B(B0→μ+μ-)<6.0×10-9 at 95% confidence level. We observe an excess of Bs0 candidates. The probability that the background processes alone could produce such an excess or larger is 0.27%. The probability that the combination of background and the expected standard model rate of Bs0→μ+μ- could produce such an excess or larger is 1.9%. These data are used to determine B(Bs0→μ+μ-)= (1.8-0.9+1.1)×10-8 and provide an upper limit of B(Bs0→μ+μ-)<4.0×10-8 at 95% confidence level. | Descripción: | 7 páginas, 1 figura.-- PACS numbers: 13.20.He, 12.15.Mm, 12.60.Jv.-- CDF Collaboration: et al. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevLett.107.191801 | URI: | http://hdl.handle.net/10261/46567 | DOI: | 10.1103/PhysRevLett.107.191801 | ISSN: | 0031-9007 | E-ISSN: | 1079-7114 |
