For those exploring quantum field theory (QFT), several key texts are recommended for study. "QFT in a Nutshell" by Zee and "Introduction to QFT" by Peskin are highlighted as excellent starting points, particularly for their focus on understanding the subject rather than just computational techniques. Ryder's QFT book is also noted for its comprehensive introduction and background information, making it a valuable resource. Additionally, "Advanced QFT" by Sakurai is mentioned, though it employs older notation. For foundational knowledge, familiarity with classical field theory and variational calculus is essential, with "Classical Mechanics" by Goldstein, Poole, and Safko suggested for review. Srednicki's QFT book is also appreciated, especially for its accessible draft PDF available online. Overall, a combination of these texts, particularly Zee and Peskin, along with Weinberg's volumes, is recommended for a successful learning experience in QFT.
