Presenting a variety of topics that are only briefly touched on in other texts, this book provides a thorough introduction to the techniques of field theory. Covering Feynman diagrams and path integrals, the author emphasizes the path integral approach, the Wilsonian approach to renormalization, and the physics of non-abelian gauge theory. It provides a thorough treatment of quark confinement and chiral symmetry breaking, topics not usually covered in other textsat this level. The Standard Model of particle physics is discussed in detail.Connections with condensed matter physics are explored, and there is a brief,but detailed, treatment of non-perturbative semi-classical methods. Ideal forgraduate students in high energy physics and condensed matter physics, the book contains many problems,which help students practise the key techniques of quantum field theory. INDICE: 1.
