Explanation of more effective effective field theory

Abstract

We show that the so-called more effective effective field theory (MEEFT) is essentially equivalent to the proper nuclear effective field theory (NEFT) in describing low-energy electroweak processes in nuclei. A key to understanding their equivalence is the relation between a NEFT-based NN-potential and a phenomenological potential through the Wilsonian renormalization group equation.We also discuss an important advantage of MEEFT.
