Electroweak decays of unflavored mesons in Poincaré covariant quark model

Abstract

This work presents the procedure for obtaining integral representation of the radiative decay constant inthe Poincaré-covariant quark model, based on Poincaré-invariant quantum mechanics. In the course of the work theauthors give numerical estimates of magnetic moments of the light quarks (u; d; s) from the V ! P decay, based onthe calculation method of the observer that was previously developed. This technique is generalized in the case of thedecay P ! V with further numerical calculation of mixing angles 􀀀′ of pseudoscalar mesons. Within the frameworkof the offered approach, we obtain a self-consistent model that describes radiative and leptonic decays of pseudoscalarand vector mesons.
