Product Description
Product Description
An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.
Ingram
This book is a clear and comprehensive introduction to quantum field theory, one that develops the subject systematically from its beginnings. The book builds on calculation techniques toward an explanation of the physics of renormalization.

This book is miserable!,
By A Customer
This review is from: An Introduction to Quantum Field Theory (Hardcover)
I consider myself to be a good physics student, I never had trouble with self study from books, if they were any good.This book is, in my opinion, just awful. The exposition of subjects is with no depth, most arguments are based on "physical intuition" that maybe professors, after many years, have - most of the time you simply don't understand why the Hell X implies Y like they say. They just slap the formulas on the page, with simply not enough justification, using all sorts of "physically obvious" or "we can expect that this will be" arguments. No depth, no depth, no depth. Look in L. Brown's book, you will see a beautifull construction of a theory, that's they way it should look like.

Good but could be better,

This review is from: An Introduction to Quantum Field Theory (Hardcover)
I used P&S for an intro QFT course. I learned much from the text as I found it clear and full of helpful examples. Particularly nice sections were those introducing free quantum fields, functional methods (path integrals), and non-abelian gauge theories and their quantization. In other sections, however, P&S often take many pages and indirect paths towards deriving basic results, which is particularly frustrating when one wishes to use the text for reference. The chapter introducing interacting fields seems disorganized, and the treatments of infrared and uv divergences (renormalization) seem to go on forever, with interesting or important results scattered through hundreds of pages. The discussion of the Standard Model is likewise overly verbose yet incomplete, and there is no discussion of susy. In this and other ways this text is less advanced than Ryder's, though I found its presentations clearer than Ryder's.Overall, I found this a nice book to learn from, but horrible to return to when I try to fill in the gaps of my understanding of QFT.

The best book on QFT,
By A Customer
This review is from: An Introduction to Quantum Field Theory (Hardcover)
This is the best book for learning and teaching quantum field theory. Although it doesn't cover philosophical or very formal aspects of QFT, it is very readable and more than sufficient to teach a year long introductory course.This book is also excellent for self study. Unlike Weinberg which is too formal or several others that are too specialized, Peskin & Schroeder presents a nice general overview of the topic.
