商品描述

Following on from the successful first (1984) and revised (1993) editions, this extended and revised text is designed as a short and simple introduction to quantum field theory for final year physics students and for postgraduate students beginning research in theoretical and experimental particle physics.

The three main objectives of the book are to:

Explain the basic physics and formalism of quantum field theory

To make the reader proficient in theory calculations using Feynman diagrams

To introduce the reader to gauge theories, which play a central role in elementary particle physics.

Thus, the first ten chapters deal with QED in the canonical formalism, and are little changed from the first edition. A brief introduction to gauge theories (Chapter 11) is then followed by two sections, which may be read independently of each other. They cover QCD and related topics (Chapters 12-15) and the unified electroweak theory (Chapters 16 – 19) respectively. Problems are provided at the end of each chapter.

New to this edition:

Five new chapters, giving an introduction to quantum chromodynamics and the methods used to understand it: in particular, path integrals and the renormalization group.

The treatment of electroweak interactions has been revised and updated to take account of more recent experiments.

商品描述(中文翻譯)

繼1984年的首版和1993年的修訂版之後,這本擴充和修訂的書籍旨在為高年級物理學生和開始進行理論和實驗粒子物理研究的研究生提供簡短而簡單的量子場論入門。

本書的三個主要目標是:

1. 解釋量子場論的基本物理和形式主義。

2. 使讀者能夠使用費曼圖進行理論計算。

3. 介紹對於基本粒子物理起著核心作用的規範理論。

因此,前十章涉及規範量子電動力學(QED)的正規形式,並且與第一版相比幾乎沒有改變。簡要介紹規範理論(第11章)之後,接著是兩個可以獨立閱讀的部分。它們分別涵蓋了量子色動力學(QCD)和相關主題(第12-15章)以及統一的電弱理論(第16-19章)。每章末尾提供了問題。

本版新增內容:

1. 五個新章節,介紹了量子色動力學以及理解它所使用的方法,特別是路徑積分和重整化群。

2. 對電弱相互作用的處理進行了修訂和更新,以考慮到更近期的實驗。
