| contents | 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, $_Ξ^{5}H $ 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. |
