Charmed and beautiful baryonic systems (hypernuclei) in chiral soliton models

TL;DR

This paper estimates the binding energies of charm and beauty hypernuclei using a chiral soliton model, highlighting the effects of flavor excitation energies and skyrmion rescaling on these energies.

Contribution

It introduces a method to incorporate flavor excitation energies into the chiral soliton model for hypernuclei, improving understanding of heavy flavor baryonic systems.

Findings

Binding energies can be partly negative for heavy flavor hypernuclei.

Skyrmion rescaling significantly affects the estimated binding energies.

Flavor excitation energies decrease the total mass of baryonic states.

Abstract

The binding energies of baryonic systems with quantum number charm or beauty and neutron excess (or large isospin) are estimated within the bound state version of the chiral topological soliton model. The procedure of the skyrmion rescaling is applied which is of importance for large enough flavor excitation energies (for heavy flavors). Inclusion of the flavor excitation energies into the minimization of the total mass of the baryonic state naturally leads to its decrease, and this effect increases with increasing flavor mass. Our results concerning the binding energies turned out to be partly negative.
