We showed the theoretical predictions within the covariant quark model of branching ratios B&sub(s) *> D&sub(s)&sup((* ))l*n&sub(l) and B&sub(c) *> M&sub(c^-c)l*n&sub(l) decays. Our results for B&sub(s) *> D&sub(s)&sup((* ))l*n&sub(l) are in good agreement with the data from the latest LHCb experiments as well as lattice quantum chromodynamics simulations. At the same time, the theoretical predictions for the ratio RJ/ψ are more than 2σ less than the experimental data. This may indicate the possibility of New Physics effects in this decay
