Srednicki's excellent QFT book is less than half price on Amazon.com at only 32$ and a few cents. I happened on this by luck and thought I would let everyone know. Dave McMahon's book on QFT in the "Demystified" series is now available but looking at a few sample pages and the content index, I was disappointed. It seems to go from very basic things (like a review of basic QM and special relativity) to the Feynman rules of a few theories with nothing in between. I did not look at everything but it does not seem like LSZ or Wick's theorem are even explained! There seems to be a bit about path integrals and even SUSY and Higgs but it is very very cursory. And the whole book is fairly short. I am not sure what the intended audience is. At the level it seems to be inteneded to, I think that Griffit's Introduction to Elementary Particle physics does a much much better job of covering the same things much more deeply. While I am babbling about books, I am in love with Aitchison's new book on supersymmetry (most of the content of the book can be found in a very long set of lecture notes that appeared in the archives but the book has a bit more stuff.). This is *the* book I have always wanted to read about SUSY! Finally someone who takes the time to explain the notation and where the equations come from! I finally understood the dotted vs undotetd notation and I understood how to obtain the SUSY transformations of the Wess Zumino model. I had tried to work with the books by Freund, Wess, Bailin and Love, Weinberg etc etc before and I had never gone very far because too much stuff was simply thrown at the reader without much motivation. I could not see the logic behind the equations so I could not really build upon the starting points. Aitchison explains things and this is so refreshing. Even if I have his set of lectures for free from the archives I decided to buy the book to reward the author for doing such a great job (his book with Hey on quantum field theory was laready one of my favorite introductory QFT books). I have also order Wesson's book on five-dimensional physics (this is no longer quantum stuff) and I am looking forward to reading that. The excerpts looked quite interesting.
