Spin effects in Bc -> Xcc + π(ρ) decays
V. A. Saleev
Abstract
The two-particle hadronic decays of Bc meson into S-wave and P-wave charmonium states Xcc are considered in the framework of hard gluon exchange model. It is shown that decay width of Bc meson into S-wave charmonium states doubly exceeds one for S-wave states. In compare with the previous estimations we predict the enhancement by 8 % the branching ratio for the Bc decays into J/psi in the two-particle hadronic decays via the contribution of the radiative decays of P-wave states in the cascade processes.
