## Quantum Field TheoryThus, 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 ù 15) and the unified electroweak theory (Chapters 16 ù 19) respectively. Problems are provided at the end of each Chapter. |
