Following on from the successful first (1984) and revised (1993)editions, this extended and revised text is designed as a short andsimple introduction to quantum field theory for final year physicsstudents and for postgraduate students beginning research intheoretical and experimental particle physics.
The three main objectives of the book are to:
Explain the basic physics and formalism of quantum fieldtheory
To make the reader proficient in theory calculations usingFeynman diagrams
To introduce the reader to gauge theories, which play a centralrole in elementary particle physics.
Thus, the first ten chapters deal with QED in the canonicalformalism, and are little changed from the first edition. A briefintroduction to gauge theories (Chapter 11) is then followed by twosections, which may be read independently of each other. They coverQCD and related topics (Chapters 12-15) and the unified electroweaktheory (Chapters 16 - 19) respectively. Problems are providedat the end of each chapter.
New to this edition:
Five new chapters, giving an introduction to quantumchromodynamics and the methods used to understand it: inparticular, path integrals and the renormalization group.
The treatment of electroweak interactions has been revised andupdated to take account of more recent experiments.
