Abstract:In this paper, we study rare decays B c → D ( * ) s,d ll within the Standard Model. The penguin, box, annihilation, color-favored cascade and color-suppressed cascade contributions are included. Based on our calculation, the annihilation and color-favored cascade diagrams play important roles in the differential branching fractions, forward-backward asymmetries, longitudinal polarizations of the final vector mesons and leptonic longitudinal polarization asymmetries. More importantly, color-favored cascade decays largely enhance the resonance cascade contributions. To avoid the resonance cascade contribution pollution, new cutting regions are put forward.

2420, 2430) or D * 2 (2460), are studied within the Standard Model. The hadronic matrix elements are evaluated in the Bethe-Salpeter approach and furthermore a discussion on the gauge-invariant condition of the annihilation hadronic currents is presented. Considering the penguin, box, annihilation, color-favored cascade and color-suppressed cascade contributions, the observables dBr/dQ 2 , A LP L , A F B and P L are calculated.

Resumen-En el presente trabajo se muestra parte del estudio del decaimiento no leptónico del mesón Bc, considerado un mesón pseudoescalar o vectorial excitado radialmente (n = 2) en el estado final, se asume la hipótesis de factorización y utiliza el modelo de quarks ISGW2. El procedimiento para obtener los anchos de decaimiento de los procesos B → P,P , B → P,V, donde B es un mesón pesado, P es un mesón seudoescalar 1 S 0 y V es un mesón vectorial 3 S 1 . Se logró medir las fracciones de decaimientos para los procesos PP y PV, se graficaron los anchos de decaimientos versus los factores de forma que provee el modelo de quarks ISGW, variando estos últimos de un 5 a un 150% de su valor original, para analizar qué implicaciones tiene en el ancho de decaimiento medido.Este estudio muestra una perspectiva y herramienta fundamental en el campo de la física de partículas, ya que los resultados encontrados no han sido calculados (o no se encuentra información de dichos cálculos), y pueden servir como herramienta para conocer algunos elementos relevantes del modelo estándar y del decaimiento no leptónico de un mesón.Palabras clave-Fracciones de decaimiento, factores de forma, constantes de decaimiento.Abstract-This paper shows part of the study of non-leptonic decay of Bc meson, pseudoscalar meson or considering a radially excited vector (n = 2) in the final state, assuming factorization hypothesis and using the quark model ISGW2. In this paper we present in detail the procedure to obtain the decay widths of the processes B → P, P, B → P, V, where B is a heavy meson, pseudoscalar meson P is a V 1 S 0 and 3 S 1 vector meson is. It was possible to measure fractions of decays to PP and PV processes, were plotted versus decay widths form factors pro- This study shows a perspective and fundamental tool in the field of particle physics, since the results are unpublished, and can serve as a tool to know some relevant elements of the standard model and the non leptonic decay of a meson.
