Hello, First I want to apologize for this FAQ-like question, but I couldn't find the answer anywhere here. so...I'm looking for a good book on quantum field theory and I'm new to this subject. I've had a introductory course on quantum mechanics. I found the following on the internet: - Peskin, Michael E., and Daniel V. Schroeder. An Introduction to Quantum Field Theory. -Weinberg, Steven. The Quantum Theory of Fields: Volume 1,2,3 -Zee. Quantum field theory in a nutshell And since I'm not planning to buy all those, I was hoping someone here could tell me which one is the best. And if you know of a book which you think is better to begin with, please tell me.
