Exact Solutions of Linearized Schwinger-Dyson Equation of Fermion Self-Energy
Abstract
Description
The Schwinger-Dyson equation of fermion self-energy in the linearization approximation is solved exactly in a theory with gauge and effective four-fermion interactions. Different expressions for the indepedent solutions which respectively submit to irregular and regular ultraviolet boundary condition are derived and expounded.
