Dressing the nucleon in a dispersion approach
S. Kondratyuk, O. Scholten
Abstract
We present a model for dressing the nucleon propagator and vertices. In the model the use of a K-matrix approach (unitarity) and dispersion relations (analyticity) are combined. The principal application of the model lies in pion-nucleon scattering where we discuss effects of the dressing on the phase shifts.
