Calculations of kaonic nuclei based on chiral meson-baryon coupled channel interaction models

TL;DR

This paper calculates kaonic nuclei using chiral meson-baryon interaction models, focusing on $K^-$-nuclear states and their dependence on different scattering amplitudes and nuclear mass number.

Contribution

It introduces a self-consistent method to derive $K^-$-nuclear potentials from various in-medium chiral scattering amplitudes, accounting for Pauli blocking effects.

Findings

$K^-$ binding energies depend strongly on the model used.

Binding energies and widths show similar dependence on nuclear mass number.

In-medium effects significantly influence the $K^-$-nuclear states.

Abstract

We present our latest calculations of $K^-$-nuclear quasi-bound states using a self-consistent scheme for constructing $K^-$-nuclear potentials from various subthreshold chirally inspired $\bar{K}N$ scattering amplitudes. We consider in-medium versions of the scattering amplitudes taking into account Pauli blocking in the intermediate states. The resulting $K^-$ binding energies as well as the widths exhibit the same A dependence, however, the binding energies strongly depend on the model used.
