Abstract
Using the divergence of the axial-vector current as the pion interpolating field and a soft-pion limit we derive a once-subtracted Low equation for the off-mass-shell πN amplitude. The σ commutator term and the once-subtracted z graphs are the main isoscalar and isovector driving terms. The calculated S-wave phase shifts are in good agreement with the experimental data when we use |gπ(4M2)|=11.69 and 25.5 MeV for the σ commutator term.
