The Non-perturbative Interaction of the Pseudovector Coupling for the Pion-nucleon Scattering
Abstract
The effect of the non-perturbative term is investigated for the pion-nucleon scattering. Including the self-energy of nucleon the cross section of the elastic scattering results in a constant value at the laboratory momentum pL ∞. The amplitude of the forward direction is applied to the dispersion relation.
