Tree amplitudes for baryon-pion scattering are studied in the 1/N_c expansion. Generalized large-N_c consistency conditions are obtained to all orders in baryon mass splittings. For baryons with spin J ~ O(1), the leading order in N_c tree amplitudes can be evaluated keeping only terms up to a given finite order in baryon mass splittings.

The Baryon-Baryon Interaction in the Large-$N_c$ Limit
hep-ph 2024-12 conditional novelty 6.0 of 10

A large-N_c analysis of the chiral baryon-baryon potential cuts the leading-order contact couplings from fifteen to three and fixes F/D=2/3 and C/D=2.
