SU(3) SYMMETRY IN STRONG COUPLING THEORY

Abstract

Although the basic assumptions and results of the "Strong Coupling Theory" are very well known, we give here a brief review of the essential features of the model, that have helped in the understanding of some experimental results in pion-nucleon interaction .__ When mesons were first considered as interacting with nucleons in analogous way to the interaction of charged particles with the electromagnetic field the theoretical results obtained, the singular nature of nuclear forces and a very large cross section for meson-nucleon scattering, were very far from the experimental facts1__ This departure from agreement with electrodynamics was considered to be due to the difference in the value of the coupling constant.
