Baryon-pion scattering in the 1/Nc expansion: Tree diagram cancellations Article uri icon

abstract

  • Tree amplitudes for baryon-pion scattering are studied in the 1/Nc expansion. Generalized large-Nc consistency conditions are obtained to all orders in baryon mass splittings. For baryons with spin J∼script O sign(1), the leading order in Nc tree amplitudes can be evaluated keeping only terms up to a given finite order in baryon mass splittings. ©2000 The American Physical Society.
