Findings

Identification of unresolved issues in chiral EFT-based nuclear force derivation

Discussion on the importance of proper renormalization techniques

Highlighting the role of sub-leading many-body forces in nuclear structure

Abstract

In spite of the great progress we have seen in recent years in the derivation of nuclear forces from chiral effective field theory (EFT), some important issues are still unresolved. In this contribution, we discuss the open problems which have particular relevance for microscopic nuclear structure, namely, the proper renormalization of chiral nuclear potentials and sub-leading many-body forces.
