Lectures in course PHYS-702: Advanced Quantum Field Theory

Quantum Field Theory: AQFT

Explores advanced Quantum Field Theory topics, including perturbativity, renormalization, and asymptotic freedom, with a focus on Amplitudes and Correlators.

Yukawa Theory: Boson Apt Function

Covers the Yukawa theory and the Boson Apt function in quantum field theory and particle physics.

Quantum Field Theory: Gauge Symmetries

Explores gauge symmetries in quantum field theory, emphasizing invariance under transformations and the role of ghost fields.

Fermion Propagator: One-loop Structure of QED

Covers the one-loop structure of Quantum Electrodynamics (QED) focusing on the vertex and the one-loop structure of QED.

Quantum Field Theory: BRST Symmetry

Covers the BRST symmetry in Quantum Field Theory, focusing on physical states and norm preservation.

QCD Ward Identity

Explains the QCD Ward identity and its implications in QED and non-Abelian gauge theory.

Renormalization of Gauge Theories
