In this talk, I want to give an overview of structure and development within the unified gauge theory of strong, weak, and electromagnetic interactions. This type of model gives anexplicitrenormalizable description of all known particles with spinJ ≤ 1, plus a few conjectured ones like W‐mesons etc. By “all”, I meanall, including such diverse particles as &rgr;‐mesons, quarks, pion, kaons, Buddha (1235) meson, &rgr;′ (1600), leptons, etc. In these models, all spectra and forces between particles derive from spontaneously broken gauge invariance and incorporate the ideas of Yang and Mills,1Weinberg,2Salam,3‘tHooft,4and others.I will begin by briefly reviewing the structure of these models, go on to describe some of the more striking results therein, and finally end by comparing these models with the “underlying‐field” or quark models advocated by other workers. Although there are some important differences, it appears that, in general, our models here (M‐models) are closely connected to the quark models‐‐the former providing a lower energy explicit realization of the latter. The M‐models also provide us with a surprising number of high‐energy bonuses.
