《量子场论》(第2卷)：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 1'5-17 with gauge theories, generalizing the familiar gauge invariance of electrodynamics to non-Abelian Lie groups.
