The Ξ-nuclear potential constrained by recent Ξ⁻ hypernuclei experiments

Abstract The Ξ-nuclear potential is investigated in the quark mean-field (QMF) model based on recent results Ξ − + 14 N ( C mathvariant="normal">Ξ − 15 ) system. experimental data binding energy of 1 p -state hyperon hypernuclei KISO, IBUKI, E07-T011, E176-14-03-35 events are merged as ${B}_{{{\Xi}}^{-}}(1p)=1.14\pm 0.11$?> B ( 1 p stretchy="false">) = 1.14 ± 0.11 MeV. With this constraint, coupling strengths between ω vector meson and fixed three QMF parameter sets. At same time, s state predicted ${B}_{{{\Xi}}^{-}}(1s)=5.66\pm 0.38$?> s 5.66 0.38 MeV with interactions, completely consistent from KINKA IRRAWADDY events. Finally, calculated symmetric nuclear matter framework. It found to be U = −11.96 ± 0.85 at saturation density, which important for discussions role strangeness a neutron star.
