Quantum Field Theory (Hardcover)

Quantum field theory is the basic mathematical framework that is used to describe elementary particles. This textbook provides a complete and essential introduction to the subject. Assuming only an undergraduate knowledge of quantum mechanics and special relativity, this book is ideal for graduate students beginning the study of elementary particles. The step-by-step presentation begins with basic concepts illustrated by simple examples, and proceeds through historically important results to thorough treatments of modern topics such as the renormalization group, spinor-helicity methods for quark and gluon scattering, magnetic monopoles, instantons, supersymmetry, and the unification of forces. The book is written in a modular format, with each chapter as self-contained as possible, and with the necessary prerequisite material clearly identified. It is based on a year-long course given by the author and contains extensive problems, with password protected solutions available to lecturers at www.cambridge.org/9780521864497.

量子場論是用來描述基本粒子的基本數學框架。這本教科書提供了對這個主題的完整和必要的介紹。假設讀者只具備本科量子力學和特殊相對論的知識，這本書非常適合開始研究基本粒子的研究的研究生。這本書以逐步呈現的方式開始，從基本概念和簡單的例子開始，然後進行歷史上重要的結果，最後深入探討現代主題，如重整化群、夸克和膠子散射的自旋-螺旋度方法、磁單極子、瞬子、超對稱和力的統一。這本書以模塊化的格式撰寫，每個章節都盡可能地獨立，並清楚標識了必要的先備知識。它基於作者開設的一年課程，並包含大量問題，解答密碼保護的解答可供講師在www.cambridge.org/9780521864497上獲取。
