Quantum Field Theory is designed as a short and simple introduction for students beginning research in theoretical and experimental physics. The three main objectives are to explain the basic physics and formalism of quantum field theory, to make the reader fully proficient in perturbation theory calculations using Feynman diagrams, and to introduce the reader to gauge theories, which play such a central role in elementary particle physics. The theory is applied first to Quantum Electrodynamics(QED) and then to the unified theory of weak and electromagnetic interactions. After studying this book, the reader should be able to calculate any process in lowest order perturbation theory for both QED and the unified electroweak theory, and in addition, calculate lowest order radiative corrections in QED using the powerful tecnique of dimensional regularisation. The Revised Edition brings the book fully up to date and makes some improvements in the treatment of dimensional regularization.
