Exotic Nuclei and Matter in a Chirally Effective Approach

TL;DR

This paper introduces a relativistic, chiral effective approach to describe nuclear matter and exotic nuclei, generating nucleon masses via meson fields, and achieves accurate finite nucleus properties while enabling broader hadronic state investigations.

Contribution

It presents a novel relativistic chiral effective framework that models nuclear forces and nucleon masses through meson fields, extending the scope of nuclear structure calculations.

Findings

Accurate calculations of finite nuclei properties.

Results for heavy and neutron-rich nuclei near the drip line.

Broader investigation of hadronic states.

Abstract

A relativistic approach to describe nuclear and in general strongly interacting matter is introduced and discussed. Here, not only the nuclear forces but also the masses of the nucleons are generated through meson fields. Within this framework it is possible to calculate properties of finite nuclei at a level of accuracy similar to dedicated relativistic nuclear structure models. Due to the more general approach, a wider range of properties of hadronic states can be investigated. A number of results for heavy and neutron-rich nuclei toward the drip line are presented.
