AN INTRODUCTION TO QUANTUM FIELD THEORY (PB 1995) Paperback

An Introduction to Quantum Field Theory is a textbook designed for graduate-level physics courses that cover relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these complex topics understandable by providing detailed, worked-out examples that illustrate the technical aspects and by offering intuitive explanations of the underlying concepts. After introducing the fundamentals of quantum electrodynamics, the book explores the theory of renormalization and its connection to statistical mechanics, as well as the renormalization group. This lays the groundwork for discussing the physical principles behind the fundamental interactions of elementary particles and their description using gauge field theories
