The Renormalization-Group Improved Effective Potential

Abstract

I will discuss the computation of the Coleman-Weinberg potential in theories with widely separated scales. There are interesting new features that arise, which requires adapting standard effective field theory methods to this problem. The formalism is applied to some well-known examples, the O(N) model in the broken phase, Higgs-Yukawa theory, and scalar theories with and without spontaneous symmetry breaking.
