Ξ⁵H hypernuclei by folding the state-of-the-art Ξ N interactions

I examined a phenomenological Nijmegen and a first principles HAL QCD Ξ N potentials to study αΞ ineractions. A Woods-Saxon type form for αΞ potential in the single-folding potential approach is derived by using the spin- and isospin averaged Ξ N interactions. The possibility of resonance or bound state is searched and accordingly, the low energy scattering phase shift parameters of αΞ are calculated. The numerical results show that even though two Ξ N potentials have significantly dissimilar isospin (I) and spin (S) components, Ξ⁵H could be only a Coulomb-assisted resonance state that appears about $ 0.5 $ MeV below the threshold of α+Ξ⁻ for both model of potentials.
