Gauge Field Theories [Paperback]

An expanded and up-dated book examining gauge theories and their symmetries.Quantum field theory forms the present theoretical framework for our understanding of the fundamental interactions of particle physics. This up-dated and expanded text examines gauge theories and their symmetries with an emphasis on their physical and technical aspects. The book contains a new introductory chapter on classical field theories and an additional chapter introducing the electroweak theory, an essential topic in any modern book on quantum field theory. This is a self-contained text for graduate courses in physics, the only prerequisite being some grounding in quantum field theory.Quantum field theory forms the present theoretical framework for our understanding of the fundamental interactions of particle physics.

This updated and expanded volume examines gauge theories and their symmetries with an emphasis on their physical and technical aspects. A new introductory chapter gives a systematic overview to classical field theories and a short discussion of their canonical quantization and the discrete symmetries C, P and T. Coverage provides a brief exposition of perturbation theory, the renormalization program, and the use of the renormalization group equation. It then explores topics of current research interest including chiral symmetry and its breaking, anomalies, and low energy effective Lals'
