- W2082091084 abstract "A modified quark meson coupling (MQMC) model is extended to include $ensuremath{Lambda}$ hyperons and $ensuremath{Xi}$ hyperons. The extended model is then used to study the equation of state (EOS) for strange hadronic matter. A weak $ensuremath{Lambda}text{ensuremath{-}}ensuremath{Lambda}$ interaction deduced from recent observation of $_{ensuremath{Lambda}ensuremath{Lambda}}^{6}mathrm{He}$ double hypernucleus is adopted in the calculation. The resultant EOS is compared with that deduced from a strong $ensuremath{Lambda}text{ensuremath{-}}ensuremath{Lambda}$ interaction. It is found that while the system with the strong $ensuremath{Lambda}text{ensuremath{-}}ensuremath{Lambda}$ interaction is more deeply bound than ordinary nuclear matter due to the opening of new degrees of freedom, the system with the weak $ensuremath{Lambda}text{ensuremath{-}}ensuremath{Lambda}$ interaction is rather loosely bound compared to the latter. It is necessary to introduce the strange mesons ${ensuremath{sigma}}^{*}$ and $ensuremath{phi}$ in the MQMC model to properly describe the interaction between the hyperons in either strong or weak $ensuremath{Lambda}text{ensuremath{-}}ensuremath{Lambda}$ interaction cases." @default.
