Novel halos in light kaonic nuclei as an indicator of nuclear equation of state at supra-normal densities

TL;DR

This paper proposes that the halo structure in light kaonic nuclei can serve as a sensitive indicator of the nuclear equation of state at supra-normal densities, linking low-density halo features to high-density nuclear matter properties.

Contribution

It introduces a novel correlation between halo structures in light kaonic nuclei and high-density nuclear matter properties using relativistic mean-field theory.

Findings

Halo size increases linearly with pressure and sound velocity square at high densities.

Halo size varies quadratically with decreasing incompressibility at saturation density.

Halo structures can indicate the nuclear EOS at supra-normal densities.

Abstract

The sensitive correlations between the low-density halo structure and the high-density properties of the nuclear equation of state (EOS) are constructed in light kaonic nuclei with the relativistic mean-field theory. More specifically, the $1p_{1/2}$ halo spreads out linearly with increasing the pressure and sound velocity square at supra-normal densities and quadratically with decreasing the incompressibility at saturation density. These results suggest that the novel halo in light kaonic nuclei can serve as a sensitive indicator of the nuclear EOS of symmetric matter at supra-normal densities.
