Title: Vacuum polarization and dynamical chiral symmetry breaking in quantum electrodynamics

Abstract

This paper considers the Schwinger-Dyson equation for the fermion mass function taking into account the vacuum polarization effects. It is shown that even in the zero-charge situation there exists, at rather large coupling constant ({alpha} {lt} {alpha}{sub c}), a solution with spontaneously broken chiral symmetry. The existence of the local limit in the model concerned is discussed.
