Abstract
On the basis of the model of hard one-gluon exchange, the two-particle hadronic decays of B c mesons into S-and P-wave charmonium states, B c → X cc π(ρ), are considered at high momentum transfers and in the nonrelativistic approximation. It is shown that the width with respect to B c-meson decay into S-wave charmonium states is two times greater than the width with respect to B c-meson decay into P-wave states and that the yield of J/ψ mesons in the cascade processes of B c-meson decay via the formation and radiative decay of P-wave charmonium states is approximately 8% of the yield of directly produced J/ψ mesons.
