Abstract
In the wake of the recent measurements of the decays BcâJ/ÏÏ(K) and BcâJ/Ïâνâ reported by the LHCb Collaboration we calculate the form factors for the BcâJ/Ï and Bcâηc transitions in full kinematical region within covariant confined quark model. Then we use the calculated form factors to evaluate the partial decay widths of the above-mentioned semileptonic and nonleptonic decays of the Bc meson. We find that the theoretical predictions on the ratios of RK+/Ï+ and RÏ+/μ+ν are in good agreement with last LHCb-data. However, the prediction for the RJ/Ï is found to be underestimated.
