Form Factor of the Relativistic Two-Particle System in the Relativistic Quasipotential Approach: The Case of Arbitrary Masses and Scalar Current

Abstract

The new relativistic form factor of the relativistic two-particle bound system in the case of scalar current is obtained. Consider­ation is conducted within the framework of relativistic quasipotential approach on the basis of covariant Hamiltonian formulation of quantum field theory by transition to the three-dimensional rela­tivistic configurational representation in the case of two interacting relativistic particles with arbitrary masses.
