Characteristic Features in Nonleptonic Hyperon Decays and Composite Models

Abstract

We summarize necessary conditions in the SU(3) frame imposed on nonleptonic hyperon decay amplitudes by studying various selection rules, and discuss relations between connectedurbaryon-diagrams and physical decay amplitudes. On the basis of a nonrelativistic weak skeleton model, we introduce 3*-model and discuss its consequences.
