Radiative decays of vector mesons in point form of Poincare-invariant quantum mechanics

Abstract

In this work we present a scheme of obtaining parameters of the model based on point form of Poincare invariant quantum mechanics. Using the integral representation of pseudoscalar and vector meson decay constants the basic parameters for u, d and s - quark sector are defined. With these numbers it is possible to estimate quark magnetic moments from V - P y decay.
