Renormalizability and nonrenormalizability of nonlocal potentials

Nuclear Theory 2025-09-11 v1

Abstract

We consider separable toy models of the nucleon-nucleon interaction inspired by chiral effective field theory. We show that nonlocality of the long-range forces causes the need for nonlocal counter terms, or even makes the whole approach nonrenormalizable.
