World Scientific Publishing Company Introduction to Quantum Field Theory (Second Edition)

Review This book is written according to natural development of physical thinking. Physical motivations, meanings and applications are clearly written with precise calculations. We can recommend this book as a good introduction to quantum field theory. --Zentralblatt MATH Product Description This book deals with quantum field theory, the language of modern elementary particles physics. Based on university lectures given by the author, this volume provides a detailed technical treatment of quantum field theory that is particularly useful for students; it begins with the quantization of the most important free fields, the scalar, the spin-1/2 and the photon fields, and is then followed by a detailed account of symmetry properties, including a discussion on global and local symmetries and the spontaneous breaking of symmetries. Perturbation theory, one-loop effects for quantum electrodynamics, and renormalization properties are also covered. In this second edition new chapters have been introduced with a general description of path integral quantization both on quantum mechanics and in quantum field theory, with a particular attention to the gauge fields. The path integral quantization of Fermi fields is also discussed.
