Abstract

In this work we study the semileptonic decays of B_c meson. We evaluated and transitions form factors in the full kinematical region within the covariant quark model. The calculated form factors are used to evaluate the semileptonic decays of B_c meson and it was defined ratios (R_ηc , R_J/ψ, R_D ,R_D*) of the branching ratios, which will be hopefully tested on LHC experiments.We compare the obtained results with the results from other theoretical approaches.
