Renormalizability and nonrenormalizability of nonlocal potentials

Year: 2025

Type: article

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.
