The Fubini-Furlan-Rossetti sum rule reexamined

Richard A. Arndt, R. L. Workman

Abstract

We review the status of a Fubini-Furlan-Rossetti sum rule for the photoproduction of pions from nucleons, indicating how well this sum rule is satisfied using a recent analysis of pion photoproduction data. Our results are discussed in light of a recent paper comparing the Gerasimov-Drell-Hearn and spin-dependent polarizability sum rules.
