The Self-energy of Nucleon for the Pole term of the Axial-vector Current and the Neutron -decay
The effect of the pion propagator on the -decay of neutron is
investigated to account for the ratio of the axial-vector to the vector part
by including the pole term. A suggestion is made that the sign and
the size of the vertex correction is appropriate to improve the discrepancy
between the result of the model hamiltonian and the experiment.Comment: 10 page
