Discusses theories that may lead to a new paradigm of particle physics, in 45 papers presented to a July 1990 workshop in Nagoya, Japan. Some of the topics are dynamical electroweak symmetry breaking with color-sextet quarks, parity violation and the origin of mass, strongly coupled lattice QED, and some non-dynamical relations in SCGT.

A follow-up of the 1988 Workshop on New Trends in Strong Coupling Gauge Theories, the 1990 Workshop, entitled Strong Coupling Gauge Theories and Beyond, is devoted to discussions on dynamical symmetry breaking and phase structure in various types of strong coupling gauge theories and other theories, their formal aspects and the related models of electroweak symmetry breaking.

This volume includes discussion on new dynamical features in the light of (deconstruted/latticized) extra dimensions, holographic QCD, Moose/hidden local symmetry, and so on. New insights into the QCD as a prototype of strong coupling gauge theories as well as in its own right, particularly in hot and dense matter are included. Sample Chapter(s). The String in an Excited Baryon (230 KB). Contents: The String in an Excited Baryon (G ''t Hooft); Mesons and Baryons from String Theory (S Sugimoto); Toy Model for Mixing of Two Chiral Nonets (A H Fariborz et al.); Strongly Interacting Matter at RHIC (C Nonaka); QED Corrections to Hadron and Quark Masses (Y Namekawa); Little Higgs M-Theory (H-C Cheng); Toward a Top-Mode ETC (H Fukano & K Yamawaki); On Cyclic Universes (P H Frampton); Large Gauge Hierarchy in GaugeOCoHiggs Unification (K Takenaga); Partially Composite Two Higgs Doublet Model (P Ko); and other papers.

This is the proceedings of the third Nagoya workshop on Strong Coupling Gauge Theories (SCGT), after SCGT 88 and SCGT 90. As a tradition of the Nagoya SCGT workshops, the focus is on dynamical symmetry breaking with particular emphasis on the nontrivial fixed points and/or large anomalous dimension, which was actually the basis of walking technicolor, strong ETC technicolor and top quark condensate, etc. Special attention is also paid to the fixed point structure in supersymmetric gauge theories, which has recently been highlighted through duality arguments.
