Paperback. Pub November 2004 489 English in World Publishing Company quantum field theory (Volume 2): This volume describes the advances in the quantum theory of fields that have led to an understanding of the electroweak and strong interactions of the elementary particles. These interactions have all turned out to be governed by principles of gauge invariance. so we start here in Chapters 15-17 with gauge theories. generalizing the familiar gauge invariance of electrodynamics to non-Abelian Lie groups.
