摘要: Abstract The di-hyperon state (DH) predicted by Jaffe in the MIT bag model is studied non-relativistic quark cluster model. resonating group method applied to ΛΛ, NΞ and ΣΣ coupled channels problem. No stable bound found below lowest ΛΛ threshold but a sharp resonance with spin-parity 0+ just threshold. structure of similar that flavour SU3 singlet attractive nature color magnetic interaction this responsible for appearance resonance. difference between present which strongly attributed mechanism confinement these two models.
