[PDF] Gauge Theories in Particle Physics: From Relativistic Quantum Mechanics to QED I.J.R. Aitchison, A.J.G. Hey

I have read a number of books on gauge field theory. This one just seems to be the clearest presentation, balanced with unerstandable problems, I have ever seen. Many physics texts leave you wishing they would get to a point. Others leave you wondering what truckload of math just ran over you. This book, and its first volume, just satisfy. Each section is clear, to the point, and enjoyable. If you want to learn some field theory, just read these books. Actually, you may need a couple of basic quantum mechanics books first. But it’s well worth it, to see the beauty of gauge theory.
