The Self-energy of Nucleon for the Pion-nucleon Scattering Parameter
Abstract
The scattering amplitude of the pion-nucleon elastic scattering is calculated by the lowest-order approximation of the perturbative expansion with the non-perturbative term. The self-energy of nucleon is determined so as to give the scattering parameters of the S-wave. It is shown that the scattering process mediated by the σ-meson plays a decisive role together with the pseudovector pion interaction.
