The Self-energy of Nucleon for the Pole term of the Axial-vector Current and the Neutron $β$ -decay

Susumu Kinpara

The effect of the pion propagator on the $β$ -decay of neutron is investigated to account for the ratio of the axial-vector to the vector part $g_{A} / g_{V}$ by including the pole term.…

The Self-energy of Nucleon for the Photoproduction of Pion in the Low-energy Region

Susumu Kinpara

The scattering amplitude of the photoproduction of $π^{+}$ is calculated using the helicity formalism. The pseudovector coupling $π$ -N interaction with the non-perturbative term is…
