Foundations of Strangeness Nuclear Physics derived from chiral Effective Field Theory

TL;DR

This paper reviews how chiral Effective Field Theory models strangeness in nuclear physics, focusing on hyperons, hyperon interactions, and their implications for dense astrophysical objects like neutron stars.

Contribution

It provides a comprehensive overview of chiral Effective Field Theory applications to strangeness nuclear physics, highlighting recent developments and open questions.

Findings

Chiral EFT effectively describes hyperon-nucleon interactions.

Hyperons may form bound states such as strange dibaryons.

Three-body forces involving hyperons are crucial for dense matter modeling.

Abstract

Dense compact objects like neutron stars or black holes have always been one of Gerry Brown's favorite research topics. This is closely related to the effects of strangeness in nuclear physics. Here, we review the chiral Effective Field Theory approach to interactions involving nucleons and hyperons, the possible existence of strange dibaryons, the fate of hyperons in nuclear matter and the present status of three-body forces involving hyperons and nucleons.
