Effective interactions of quarks and static hadron properties

Within the framework of the relativistic model with universal potential of quark interaction hadron static properties are investigated. The model is based on the choice of the universal potential of qq- interaction, determining effective quark interaction in multiparticle systems. The calculation of masses, magnetic moments radiative meson decay widths baryons and exotic multiquark hadrons is performed. Quark dimensions and ''hyper-- fine'' structure of hadron radial excitations are discussed as well
