The construction of the electromagnetic current operator for the process of decay of the rho-meson in the different form of the Poincare-invariant quantum mechanics

Abstract

This work is devoted to the description of radiation decays V → Pγ in the framework of Poincareinvariant quantum mechanics (PIKM). A procedure developed for constructing the operator of the electromagnetic current of the transition with different values of the total angular momentum with respect to the conditions of the Lorentz covariance and conservation. As the figures of this approach in a modified relativistic impulse approximation held description of the radiative transition in the instant form PIKM. The construction of the electromagnetic current operatorRoman Polezhaev Construction of the operator of the electromagnetic current of the transition to a system of noninteracting particlesIn this paper, we consider the electromagnetic current system of two noninteracting particles.State vector of the one of a free particle in the instant form PIKM can be represented as follows:| p, M, j, m .(2.1)
