Dynamical Theory of Hadron Interactions Based upon Extended Particel Picture. II: Construction of the Hadron Interactions

Abstract

The interaction of hadron is discussed on the basis of an extended particle model. We assume that the interaction between hadrons is clue to the coupling between currents carried by excitons excited in the particles, which is mediated by some intermediate field. This picture enables us to write clown all hadron interactions once this original interaction be­ tween excitons is given -thus leading to a more unified and a dynamical understanding of the hadron interactions. As examples 71-71, K-N and 11-N interactions are discussed. As far as the comparison is possible, the resulting meson-meson interactions and the meson­ baryon interactions are in agreement with those obtained by SU, or its relativistic generali­ zation. But a great advantage of our model is that it gives furthermore new relations between these meson-meson interactions and meson-baryon interactions because of its unified structure. For example, we find that in our model the coupling constant for the pnn inter­ action g' is related to the (pseudo-scalar) 11-N coupling constant g by where mp, m and lvl denote respectively the mass for p, 71 and the nucleon. This relation Is satisfied very well experimentally.
