Title: Baryon-pion scattering in the 1/N{sub c} expansion: Tree diagram cancellations

Abstract

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