I examined a phenomenological Nijmegen and a first principles HAL QCD $\Xi N$ potentials to study $\alpha\Xi$ ineractions. A Woods-Saxon type form for $\alpha\Xi$ potential in the single-folding potential approach is derived by using the spin- and is

The $\Xi N$ interaction plays an important role in our understanding on the long-anticipated $H$-dibaryon. Recent lattice QCD calculations verified the attractive nature of the $\Xi N$ interaction. On the other hand, whether it is strong enough to ge

A new way to study the spin-isospin dependence of the $\Xi N$ interaction is explored through the energy levels of $\Xi N\alpha$ and $\Xi N\alpha \alpha$ systems with $\alpha$ being a spectator to attract the $ \Xi N$ pair without changing its spin-i

We study the energy spectra of $\Xi$ hypernuclei $^{15}_{\Xi}$C and $^{12}_{\Xi}$Be with a relativistic mean field (RMF) model with meson exchange $\Xi N$ interactions. The RMF parameters are optimized to reproduce the average energy of KINKA and IRR

The $\Xi N$ interaction is investigated in the quark mean-field (QMF) model based on recent observables of the $\Xi^-+^{14}\rm{N}$ ($_{\Xi^-}^{15}\rm{C}$) system. The experimental data about the binding energy of $1p$-state $\Xi^-$ hyperon in $_{\Xi^

Experimental evidence exists that the $\Xi$-nucleus interaction is attractive. We search for $NN\Xi$ and $NNN\Xi$ bound systems on the basis of the AV8 $NN$ potential combined with either a phenomenological Nijmegen $\Xi N$ potential or a first princ

The in-medium properties of a baryon-baryon interaction for the strangeness $S=-2$ sector derived within chiral effective field theory up to next-to-leading order are investigated. The considered $\Xi N$ interaction is in line with available empirica

We study the non-mesonic weak decay of the doubly-strange hypernucleus $^{\Lambda\Lambda}_6$He within a model which considers the exchange of pseudoscalar and vector mesons. Special attention is paid into quantifying the strong interaction effects, f
