This completely revised and updated graduate-level textbook is an ideal introduction to gauge theories and their applications to high-energy particle physics, and takes an in-depth look at two new laws of nature--quantum chromodynamics and the electroweak theory. From quantum electrodynamics through unified theories of the interactions among leptons and quarks, Chris Quigg examines the logic and structure behind gauge theories and the experimental underpinnings of today's theories. Quigg emphasizes how we know what we know, and in the era of the Large Hadron Collider, his insightful survey of the standard model and the next great questions for particle physics makes for compelling reading. The brand-new edition shows how the electroweak theory developed in conversation with experiment. Featuring a wide-ranging treatment of electroweak symmetry breaking, the physics of the Higgs boson, and the importance of the 1-TeV scale, the book moves beyond established knowledge and investigates the path toward unified theories of strong, weak, and electromagnetic interactions. Explicit calculations and diverse exercises allow readers to derive the consequences of these theories.
Extensive annotated bibliographies accompany each chapter, amplify points of conceptual or technical interest, introduce further applications, and lead readers to the research literature. Students and seasoned practitioners will profit from the text's current insights, and specialists wishing to understand gauge theories will find the book an ideal reference for self-study.

Reviews for Gauge Theories of the Strong, Weak, and Electromagnetic Interactions: Second Edition
It is hard to find words to describe Quigg's clean, high-quality work: as an author he is a virtuoso performer. --Johann Rafelski, CERN Courier Gauge Theories of the Strong, Weak, and Electromagnetic Interactions will, for many years, remain as a standard textbook in particle theory. I highly recommend it for a two-semester advanced graduate course in particle physics and as a valuable addition to the collection of every particle physicist. --Rabi Mohapatra, Physics Today I find this book extremely useful, because it signifies the importance of modern ideas and perspectives in particle physics. --Gert Roepstorff, Zentralblatt MATH
