Abstract: A brief review of the current state of observed deviations of theoretical predictions from experimental data in semileptonic decays of B and Bc mesons is given. A theoretical analysis of these decays is carried out, taking into account the effects of new physics, which appear due to the introduction of new four-fermion operators, which are absent in the basis of the Standard Model (SM) operators. The necessary form factors are calculated within the framework of the covariant quark model developed in our papers.
