Production of K mesons in exclusive $B_c$ decays

Abstract

The paper is devoted to investigation of $K$ mesons production in exclusive $B_c$ decays $B_c\to {\psi }^{{(}^{\prime })}{K}^{+}{K}^{-}{\pi }^{+}$ and $B_c\to {\psi }^{{(}^{\prime })}{K}^{+}{\pi }^{+}{\pi }^{-}$. In the framework of resonance approximation we obtain theoretical predictions for branching fractions of these decays and present distributions over different kinematical variables.
