Abstract

We have computed branching ratios of two-body nonleptonic B_c → X_ccM decays, where X_cc is the radially excited charmonium η_c(2S) or ψ(2S) meson, and M is a pseudoscalar (P) or a vector (V) or an axial-vector (A(³P₁)) meson. We have assumed factorization hypothesis and calculated the form factors in the nonrelativistic ISGW2 quark model. We have found that some of these decays have branching ratios of the order of 10^-3 - 10^-4.
