Field-theory approach to the disintegration of bound systems on the basis of a local gauge nature of an electromagnetic field

Abstract

An approach is developed that makes it possible to take into account the structure of bound (nonlocal) matter fields in photodisintegration processes with allowance for the requirements of the fundamental principles of covariance and gauge invariance. The approach is based on employing the local U(1) gauge nature of an electromagnetic field, whose vector potential is identified with a connection that performs a parallel transportation of matter-field operators in a fiber space with an interior charge symmetry along “minimum” trajectories.
