DISCLAIMER: Very rough notes from class, with some additional side notes.
These are notes for the UofT course PHY2403H, Quantum Field Theory I, taught by Prof. Erich Poppitz fall 2018.
Relativistic normalization.
We will continue looking at the generator of spacetime translation \( \hatU(\Lambda) \), which has the property \begin{equation}\…
