The Self-energy of Nucleon for the Pion-nucleon Scattering Parameter

Susumu Kinpara

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 se…

The Self-energy of Nucleon for the Photon-proton Elastic Scattering and the Electromagnetic Polarizability

Susumu Kinpara

The effect of the self-energy on the photon-proton elastic scattering is investigated for the backward and the forward directions. The shape of the Thomson scattering at the photon…

The Non-perturbative Interaction of the Pseudovector Coupling for the Pion-nucleon Scattering

Susumu Kinpara

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…

The Self-energy of Nucleon in the Pseudovector Coupling Pion-nucleon System for the Electromagnetic Form Factor of Proton

Susumu Kinpara

The electromagnetic form factor of proton is studied following our previous calculation of the anomalous magnetic moment. The non-perturbative term is incorporated to correct the $…

The Self-energy of Nucleon for the Anomalous Magnetic Moment

Susumu Kinpara

The anomalous part of the magnetic moment of nucleon is studied. The electromagnetic vertex of nucleon is calculated using the pseudovector coupling pion-nucleon interaction. The s…

Relation between the Vertex Function and the Propagators in the Pseudovector Coupling Pion-Nucleon System

Susumu Kinpara

The procedure for deriving the Ward-Takahashi identity is applied to the pseudovector coupling pion-nucleon system in which the isovector and axial-vector current does not conserve…
