The Non-perturbative term of the Pseudovector Interaction in the Pion-Nucleon System and the Pion Form Factor

Abstract

The correction of the higher-order process for the photon-pion-pion vertex is calculated by the field theoretical method of the pion-nucleon system. The non-perturbative term of the pseudovector coupling interaction is included to examine the effect of the self-energy.
