Gauge theory and renormalization (Erice, August 1994)

TL;DR

This paper reviews the historical development of renormalizable non-Abelian gauge theories, highlighting their impact on understanding particle physics and the interplay of mathematics and symmetry.

Contribution

It provides a personal perspective on the early progress and significance of gauge theories in unifying fundamental interactions.

Findings

Enhanced understanding of gauge theory role in particle physics

Connection between symmetry, topology, and field theory

Foundation for modern Standard Model development

Abstract

Early developments leading to renormalizable non-Abelian gauge theories for the weak, electromagnetic and strong interactions, are discussed from a personal viewpoint. They drastically improved our view of the role of field theory, symmetry and topology, as well as other branches of mathematics, in the world of elementary particles.
