Abstract

I examined a phenomenological Nijmegen and a first principles HAL QCD ΞN 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 ΞN 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 ΞN 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.
