Recent Progress in Dispersion Theoretical Approach to Nuclear Forces

Abstract

I have been asked to give a brief report on the progress of the dispersion theoretical approach to the two nucleon interaction. Indeed, during the last few years, this approach has been successful in providing a good understanding of the NN forces — at least for long and medium ranges — and at the same time a good quantitative fit of the data. The fact is noteworthy since the whole scheme is based on properties as fundamental as unitarity, analyticity and crossing. A rather detailed account was reported last year at the Vancouver Conference¹ and to avoid repetition, I shall limit myself here only to the progress which has been achieved during the elapsed year.
