Derived from lectures presented by the author at the University of Heidelberg, this text provides graduate students with an excellent account of the main elements of the modern theory of elementary particles. Though necessarily a good deal of attention is given to formal matters, the author has been at pains to keep ever in focus the physics of the matters at hand. Twenty-seven chapters, under four topical heads: Relativistic kinematics and quantum fields; Quantum electrodynamics; The Strong interaction; The Electroweak interaction. Good bibliography and ten appendices, of which one provides solutions of selected exercises. Typography (particularly of the mathematical material) exceptionally easy on the eye. Available in cloth at 98.00. (NW) Annotation copyright Book News, Inc. Portland, Or.
