Abstract

An iterative procedure is developed for solving the Schwinger-Dyson equation for the coupled nucleon and pion propagators for the case when vertex corrections are neglected. The presence of ghost poles in the dressed propagators is avoided by using explicitly only the imaginary part of the propagators, eliminating the real part through a dispersion relation.
