From the reviews: "I was looking recently for an introductory book to supersymmetry for a student beginning his "memoire", and was somewhat at a loss. I needed a basic introduction, with the essential of the motivation and the construction of Lagrangians. In the same time, such a discussion is impossible without some consideration of the "ugly part" of supersymmetry, namely soft breaking terms and their motivation. Here I did not want to fall in the infinite number of reviews covering a forest of "natrual" models, but wanted rather some basic principles, and even more important, a critical approach. You guess it: this is exactly what I found in the book of Polonsky. [...] An outstanding book, and a very compact, critical introduction to supersymmetry, I consider this to be required buying for any graduate library." (Physicalia, 2002)
