Quantum field theory is the basic mathematical framework that is used to describe elementary particles. This textbook provides a complete and essential introduction to the subject. Assuming only an undergraduate knowledge of quantum mechanics and special relativity, this book is ideal for graduate students beginning the study of elementary particles. The step-by-step presentation begins with basic concepts illustrated by simple examples, and proceeds through historically important results to thorough treatments of modern topics such as the renormalization group, spinor-helicity methods for quark and gluon scattering, magnetic monopoles, instantons, supersymmetry, and the unification of forces. The book is written in a modular format, with each chapter as self-contained as possible, and with the necessary prerequisite material clearly identified. It is based on a year-long course given by the author and contains extensive problems, with password protected solutions available to lecturers at www.cambridge.org/9780521864497.
'This accessible and conceptually structured introduction to quantum field theory will be of value not only to beginning students but also to practicing physicists interested in learning or reviewing specific topics. The book is organized in a modular fashion, which makes it easy to extract the basic information relevant to the reader's area(s) of interest. The material is presented in an intuitively clear and informal style. Foundational topics such as path integrals and Lorentz representations are included early in the exposition, as appropriate for a modern course; later material includes a detailed description of the Standard Model and other advanced topics such as instantons, supersymmetry, and unification, which are essential knowledge for working particle physicists, but which are not treated in most other field theory texts.' Washington Taylor, Massachusetts Institute of Technology
'Over the years I have used parts of Srednicki's book to teach field theory to physics graduate students not specializing in particle physics. This is a vast subject, with many outstanding textbooks. Among these, Srednicki's stands out for its pedagogy. The subject is built logically, rather than historically. The exposition walks the line between getting the idea across and not shying away from a serious calculation. Path integrals enter early, and renormalization theory is pursued from the very start.... By the end of the course the student should understand both beta functions and the Standard Model, and be able to carry through a calculation when a perturbative calculation is called for.' Predrag Cvitanovi, Georgia Institute of Technology
'This book should become a favorite of quantum field theory students and instructors. The approach is systematic and comprehensive, but the friendly and encouraging voice of the author comes through loud and clear to make the subject feel accessible. Many interesting examples are worked out in pedagogical detail.' Ann Nelson, University of Washington
'I expect that this will be the textbook of choice for many quantum field theory courses. The presentation is straightforward and readable, with the author's easy-going 'voice' coming through in his writing. The organization into a large number of short chapters, with the prerequisites for each chapter clearly marked, makes the book flexible and easy to teach from or to read independently. A large and varied collection of special topics is available, depending on the interests of the instructor and the student.' Joseph Polchinski, University of California, Santa Barbara
Further, Srednicki is very well laid out, and each chapter makes sense where it is. Even if you disagree with some of the chapter placement, the book is written in a modular way, so it's pretty easy to mix and match material. (Comparing it to P&S again, P&S is not written in either a logically sound way nor is it modular). Path integrals are introduced earlier, which I believe is the easier way to learn how to derive Feynman rules. The book also anticipates renormalization from the beginning, so it's not a huge surprise when it finally happens.
However, the books main scalar theory of choice is phi^3, which is an uncommon theory in other textbooks/classes. Because of this, it's not always the best reference, since most classes expect you to understand phi^4 instead, so homework assignments will be closer to Phi^4. So when it's time to get your hands dirty and really work something out, it is the case (at least for me) that a different book is in order. Of course, if your professor wants to stick close to the book, or if you are studying on your own, neither of these are a problem.
Finally, the homework problems are actually pretty good. They're short enough to be reasonable (unlike some other textbooks) but at the same time they are interesting and cover a lot of material. As mentioned by another reviewer, there is a field redefinition problem that is exceptionally good.
