Pion-Nucleon Scattering in Baryon Chiral Perturbation Theory combined with the $1/N_c$ Expansion

D. Jayakodige, J. L. Goity

This work implements the combined BChPT and 1/Nc expansions for pion-nucleon elastic scattering. The effective theory is based on the baryon sector dynamical spin-flavor SU(4) symm…
