BARRIOS AVILA, Juan Carlos; SANABRIA GOMEZ, José David  and  MUNOZ NUNGO, José Herman. Nonleptonic B_c decays, radial and excited charmonium mesons in the final state. Iteckne [online]. 2013, vol.10, n.1, pp.21-26. ISSN 1692-1798.

This paper shows part of the study of non-leptonic decay of B_c 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 ¹S₀ and ³S₁ vector meson is. It was possible to measure fractions of decays to PP and PV processes, were plotted versus decay widths form factors providing ISGW the quark model, the latter varying from 5 to 150% of its original value, to analyze what implications does this have on the measured decay width. This study shows a perspective and fundamental tool in the field of particle physics, since the results are unpublished, and can serve as a tool to know some relevant elements of the standard model and the non leptonic decay of a meson.

Keywords : Fractions of decays; widths form factors; decay constants.
