Review: It is a very good introcutory course. - Wonderful book, good price.
Review: A good book for those who have read Ryder or its equivalent, with an very readable chapter on the Higgs model - Peskin and Schroeder's book seems to be the standard text for courses in quantum field theory these days. Although somewhat intimidating for the novice, the reader seasoned by reading a good portion of Ryder's book Quantum Field Theory will find himself fairly comfortable. The advantages of the compact (1, sigma) notation used by the authors for Dirac spinors and gamma matrices, although not as immediately transparent as the expressions favored by Ryder, soon become familiar. The use of a more compact notion gives more space for narrative exposition. One discussion that I found particularly helpful in P&S is the explanation for the sign of time dependence for the field operator psi(x) on p.54 using equations (3.91) and (3.92). Because psi(x) is an operator and not a simple wave function, we have to switch to the Heisenberg picture in order for it to have time dependence. In the Heisenberg picture the annihilation operator has time dependence a(p)exp(-iE(p)t). It is then clear that the annihilation side of psi(x) must be proportional to a(p)exp(-p.x), since p.x=(Et-P.r) using Ryder's choice of metric and space time coordinates (with P as the three momentum, r as the three position [x,y,z], and E as the energy). Perhaps this seems like a minor point, but the choice of sign for the exponential in a(p)exp(-p.x) seemed to me to be purely arbitrary before reading this section in P&S. As you might expect, however, some points that should either be given greater emphasis--or explained in more detail are sometimes glossed over. Happily, a good supplement for this text exists in the lecture notes of Cambridge University's David Tong. Tong's notes provide a better understanding of the ideas behind the rotation of the contour slightly away from the real axis (p.95) in order to insure that the integral for the propagator converges. Tong also adds to the authors' discussion of normal ordering and Wick's Theorem. Peskin and Schroeder also provide a very readable discussion of the Higg's model in Chapter 20. Reading this chapter has given me the best appreciation for QFT that I have gleaned thus far.

### ⭐⭐⭐⭐⭐ It's the standard textbook for a reason
*by A***R on June 10, 2021*

Peskin and Schroeder's textbook is the standard textbook for quantum field theory courses for a reason. Although it may be a little intimidating for beginners, it covers an almost unmatched breadth and depth of material extremely well, and also teaches actual calculation very well.
