Description
The leptonic decays of heavy quarkonia are complementary observables to the semileptonic decays of heavy mesons and provide additional insight into the possible lepton flavor universality breaking. These decays are analyzed in the framework of the covariant confined quark model by using a novel approach for the description of the radially excited quarkonia states. It turns out that the experimental data can be described by our approach within the Standard Model without introducing the new physics operators.
