Naturalness of the Coleman-Glashow Mass Relation in the 1/N_c Expansion: an Update
Elizabeth Jenkins🇺🇸 · Richard F. Lebed🇺🇸
Abstract
A new measurement of the Xi^0 mass verifies the accuracy of the Coleman-Glashow relation at the level predicted by the 1/N_c expansion. Values for other baryon isospin mass splittings are updated, and continue to agree with the 1/N_c hierarchy.
