Pionic dressing of baryons in chiral quark models

Abstract

We present a method for constructing the complete set of meson-exchange corrections to baryon observables described by covariant chiral quark models. The meson corrections are expressed in terms of an unperturbed valence-quark Green's function. This method is illustrated for the case of an NJL model. It also enables us to discuss, in terms of approximations used for this unperturbed Green's function, the treatments of meson corrections in two other chiral quark models.
