CSIC ORCID; Cabrera, Susana CSIC ORCID; Zucchelli, S.; CDF Collaboration | Fecha de publicación: | 1-jun-2009 | Editor: | American Physical Society | Citación: | Physical Review D - Particles, Fields, Gravitation and Cosmology 79(11): 112003 (2009) | Resumen: | We report a measurement of the ratio of branching fractions of the decays B±→J/ψπ± and B±→J/ψK± using the CDF II detector at the Fermilab Tevatron Collider. The signal from the Cabbibo-suppressed B±→J/ψπ± decay is separated from B±→J/ψK± using the B±→J/ψK± invariant mass distribution and the kinematical differences of the hadron track in the two decay modes. From a sample of 220pb-1 of pp̄ collisions at s=1.96TeV, we observe 91±15 B±→J/ψπ± events together with 1883±34 B±→J/ψK± events. The ratio of branching fractions is found to be B(B±→J/ψπ±)/ B(B±→J/ψK±)=(4.86±0.82(stat)±0.15(syst))%. © 2009 The American Physical Society. | Versión del editor: | http://doi.org/10.1103/PhysRevD.79.112003 | URI: | http://hdl.handle.net/10261/226726 | DOI: | 10.1103/PhysRevD.79.112003 | Identificadores: | doi: 10.1103/PhysRevD.79.112003 issn: 1550-7998 |
