The Effect of Pion Exchange in a Relativistic Quark Model of Baryons

Abstract

We examine the effect of adding pion exchange between quarks and pion self-energy corrections to the Los Alamos Relativistic Quark model with a short distance cutoff of the Bethe form. The contributions to the nucleon and the Delta-baryon are small. We conclude that the model is stable under this change in the sense that significant changes to the model parameters are not required.
