Light Baryon Resonances: Restrictions and Perspectives
Ya. I. Azimov, R. A. Arndt, I. I. Strakovsky, R. L. Workman
Abstract
The problem of nucleon resonances N' with masses below the Delta is considered. We derive bounds for the properties of such states. Some of these are new, while others improve upon existing limits. We discuss the nature of N' states, and their unitary partners, assuming their existence can be verified.
