Волновые функции и S-фактор составной системы двух релятивистских спиновых кварков произвольных масс

Abstract

In the framework of the Hamiltonian formulation of quasipotential approach in quantum field theory by transition to the three-dimensional relativistic configurational representation the exact solutions of the covariant two-particle equations, mass spectrum, and S factor are obtained for a system of two relativistic spin-1/2 quarks with arbitrary masses interacting via a Coulomb-like chromodynamical potential. The cases of the pseudoscalar, vector, and pseudovector are considered. The new regularities has been installed in behavior of threshold resummation S-factor.
