Here is a link to [a PDF with my notes for the final QFT I lecture.] That lecture followed [1] section 5.1 fairly closely (filling in some details, leaving out some others.)
This lecture
Introduced an interaction Lagrangian with QED and QCD interaction terms \begin{equation*} \LL_{\text{QED}} = – \inv{4} F_{\mu\nu} F^{\mu\nu} + \overline{\Psi}_e \lr{ i \gamma^\mu \partial_\mu – m } \Psi_e – e…
