At this level, I prefer Quantum Field Theory for Mathematicians by Robin Ticciti. This is an excellent quantum field theory book, and, in spite of its title, is not a tome on axiomatic quantum field theory, or a book that emphasizes mathematical rigour. Its presentation is, however, a little less fuzzy than presentations in many other books. It shows how to calculate physical things like cross sections, and is a serious competitor for standard works like Peskin and Schroeder. I wish this book had been available when I was a grad student!

Ok. I purchased the book. However, I am having a hard time following what the author is even trying to explain. It could be the language or my mathematical immaturity - I have no idea. I guess I will just keep trying....

For example, can anybody tell me what the author is trying to say and the logic behind what he is saying in the following two paragraphs?

I am pretty sure I do not have the prerequisite to read this book effectively, but I can't help but thinking, the presentation may be quite fuzzy!

What background do I need to read and understand this book? I know QM (from Sakurai and a few others). I do understand SR and GR. However, I do not know much of group theory or lie algebra or a ton of Hilbert Space formalism.

If you are looking for a context in which the author explains the paragraphs that I mentioned, you could look at this excerpt.

From the aforementioned book :

The prerequisites for this presentations are (1) familiarity with Hilbert-space formalism of quantum mechanics (2) assimilation of basic principles of special relativity (3) a goodly measure of mathematical maturity

Thanks. Still I am no longer sure the book is written in a clear language or suitable for a beginner.

Concerning your physics questions, I suggest you ask in the QT forum. For a quite elementary treatment of the representation theory of the Poincare group, see my QFT manuscript (Appendix B):

Another very good book for preparation of learning relativistic QFT is

Sexl, Urbandtke, Relativity, Groups, Particles, Springer Verlag
