Abstract: In this paper we showed the theoretical predictions within the covariant quark model of branching ratios and decays. Our results for are in a 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 are more than 2σ less than the experimental data. This may indicate on the possibility of New physics effects in this decay.
