This is where the book gains its fearsome reputation. Chapters 4-6 cover Feynman diagrams, propagators, and the renormalization of QED. However, while a modern text like Peskin & Schroeder holds your hand through the computation of the electron anomalous magnetic moment, Itzykson-Zuber presents the material in a dense, theorem-proof style. They derive the Ward-Takahashi identities with elegant rigor, then tackle renormalization using the BPHZ (Bogoliubov-Parasiuk-Hepp-Zimmermann) method—a notoriously technical approach that many other texts avoid.
