Electroweak characteristics of mesons in the relativistic quark model

In this work the electromagnetic radius and the polarizability of the mesons are obtained by use of the effective Lagrangians constructed on the one hand with taking into account of general principles of the relativistic quantum field theory and on the other hand with taking into account of the compound relativistic model meson representation. Also using a relativistic constituent quark model based on point form of Poincare-covariant quantum mechanics we calculated electromagnetic radius and the decay constants of the mesons with spinor quarks.
