BC_NPI module for the analysis of Bc -> J/psi +n pi and Bc -> B_s +n pi decays within the EvtGen package

A. V. Berezhnoy, A. K. Likhoded, A. V. Luchinsky

The module for the generation of $B_c$ meson decays into $J/\psi +n\pi$ and $B_s^{(\ast )}+n\pi$ ($n\le 4$) is implemented into EvtGen program package. The decay amplitudes are calculated i…
