Physics 583 (QFT II) Spring 2021 zoom lecture on Thursday March 16, 2021. Today we solved the Callan-Symanzik equation and investigated the nature if the solutions at a fixed point (and in the vicinity of the fixed point) and introduced the concept of anomalous dimension of the field operator. We used these concepts to find the beta function and the anomalous dimension of 𝜙^4 theory (including corrections to scaling).
