Second-Class Currents: Some Model-Independent Considerations and Conclusions

Abstract

We study the problem of second-class currents, and attempt to clarify the situation, by working within the framework of a formulation that makes no appeal to any specific dynamical model of hadronic interactions or nuclear structure. While much of the paper is pedagogical, several new theorems and results are presented. The import of recent experiments is discussed, and a scheme for classification of second-class currents is proposed.
