Hyperon halo structure of C and B isotopes

TL;DR

This paper investigates hyperon halo structures in C and B isotopes using a Hartree-Fock model, revealing extended hyperon wave functions and potential experimental signatures of halo phenomena.

Contribution

It introduces the first theoretical prediction of hyperon halo structures in light C and B isotopes using Skyrme-type interactions.

Findings

Hyperon 1p-state exhibits halo structure with extended wave function.

Calculated $\Lambda$ binding energies match experimental data.

Enhanced electric dipole transition suggests hyperon halo presence.

Abstract

We study the hypernuclei of C and B isotopes by Hartree-Fock model with Skyrme-type nucleon-nucleon and nucleon-hyperon interactions. The calculated $\Lambda$ binding energies agree well with the available experiment data. We found halo structure in the hyperon $1p$-state with extended wave function beyond nuclear surface in the light C and B isotopes. We also found the enhanced electric dipole transition between $1p$- and $1s$-hyperon states, which could be the evidence for this hyperon halo structure.
