Quantum Field Theory for Experimentalists and Beyond

About This Book

Volume I of the two-volume graduate textbook on quantum field theory, written by Dmitry V. Naumov — Breakthrough Prize laureate and Deputy Director of the Dzhelepov Laboratory of Nuclear Problems at JINR, Dubna.

This volume covers the foundational structure of QFT through its advanced formalism: canonical quantization, propagators, the S-matrix, Feynman diagram techniques, loop corrections, renormalization, and gauge field theory. Unlike many introductory treatments, this textbook is written for physicists who work with experiment — every formalism is grounded in physical reasoning, not axiomatic abstraction.

What You Will Learn

• Classical field theory: Lagrangians, Noether's theorem, symmetry currents
• Canonical quantization of scalar, spinor, and vector fields
• The S-matrix, LSZ reduction, and scattering amplitudes
• Feynman rules: derivation, application, and physical interpretation
• One-loop corrections, regularization, and renormalization theory
• Abelian gauge theories and quantum electrodynamics (QED)
• Ward identities, symmetry constraints, and radiative corrections

Who This Book Is For

Graduate students in physics and advanced undergraduates who have completed classical mechanics, electrodynamics, and introductory quantum mechanics. Also valuable for working physicists and postdocs who need a rigorous reference grounded in physical applications.

Format Note

This is a fixed-layout PDF preserving all mathematical typesetting, Feynman diagrams, and figures exactly as in the print edition. Best experienced on a tablet or laptop screen. Not optimized for e-ink readers.
