This is the best textbook for quantum field theory (QFT), written by one of the master in this field. It is however not a book that you should start learning QFT with, instead I would suggest new comer to start with Maggiore's book, slowly moves on to Peskin Schroeder, and finally Weinberg's QFT 1
and 2. Basically every question that you can think about, the answer will be somewhere inside this…mehrThis is the best textbook for quantum field theory (QFT), written by one of the master in this field.
