Description

This lecture covers the one-loop structure of Quantum Electrodynamics (QED) focusing on the vertex and the one-loop structure of QED. The slides discuss the one-loop structure of QED, the vertex, and the calculation of the fermion propagator. The instructor explains the process of integrating by parts and simplifying the expressions to obtain the fermion propagator. The lecture concludes with a detailed explanation of the counter terms and the consistent renormalization of the Lagrangian in terms of bare fields.
