Gauge Field Theories

Written as a textbook for graduate courses in physics, this book examines gauge field theories and symmetries with an emphasis on their physical and technical aspects. Included is a brief introduction to perturbation theory, the renormalization program, and the use of renormalization group equation. Topics of current research are also covered, such as chiral symmetry and its breaking, anomalies, and low energy effective lagrangians. The only prerequisite is a familiarity with path integrals and quantum field theory.
