Electromagnetic Characteristics of $$c\bar {c}$$- and $$b\bar {b}$$-Systems in the Relativistic Quark Model

This paper presents an original method for calculating the masses of constituent c- and b-quarks in a model based on the composite quark model and the point form of Poincaré-invariant quantum mechanics. It is shown that using the quark-antiquark potential and the integral representation of the vector meson decay $$V \\to {{\\ell }^{ + }}{{\\ell }^{ - }}$$ constant leads to mass and magnetic moment values consistent with the results of other models.
