Lecture 4 The Beta Function and Renormalization Group Flow

rg beta function Lecture 4 The Beta Function and Renormalization Group Flow In the previous lecture we have seen how to compute the beta function by using the renor-maliza. ion procedure resulting in the counterterms of the theory. The Callan-Symanzik equation is. particularly useful in the context of perturbation theory. Howev..
