SYMANZIK APPROACH IN MODELING THE INTERACTION OF QUANTUM FIELDS WITH EXTENDED OBJECTS: SCATTERING OF DIRAC PARTICLES ON MATERIAL PLANE

摘要

The model is constructed within the Symanzik approach to describe the interaction of fields of quantum electrodynamics with extended objects. The scattering of a Dirac particle on a homogeneous and isotropic material plane is studied. Results are obtained and presented for transmission and reflection amplitudes of a plane wave, for a given polarization, energy, and momentum, as functions of the model parameters. The transmission and reflection coefficients are given for particles motion in the orthogonal to the plane direction.
