Magnetic moment of ρ-meson in point form of Poincaré-invariant quantum mechanics

Abstract

In the framework of relativistic quark model based on the point form of Poincaré- invariant quantum mechanics the magnetic moment of the ρ-meson is calculated taking into account the internal structure of quarks. It ’s shown that the model parameters obtained from the condition of matching theoretical calculations with experimental data on lepton and radiative decays of hadrons lead to the results that correlate with calculations in models based on the front and instant forms of dynamics.
