Dispersion Relation Methods in Strong Interactions

Abstract

In writing this review we have realized that we were dealing with a large amount of extremely heterogeneous material. The very impressive develop ment of ideas in the last years has not yet led to a self-contained satisfactory theory, although the numerous avenues of theoretical development have all attained partial success. Hence a physicist interested in applications-to whom this article is mainly devoted-has to rely on rather heterogeneous sources.
