Phase-Shift Definition for Pion-Nucleon Scattering from Chiral Perturbation Theory
Chiral Perturbation Theory is considered as a very precise method when applied to pion-nucleon scattering nearthreshold and in the unphysical region since in these cases the pion momenta are small. In this framework, thirdorder calculation yields a non-relativistic scattering amplitude with nine fre...
