| contents | The production of doubly strange hyperon $Ξ^-$ and trebly strange hyperon $Ω^-$ in relativistic Au+Au collisions at $\sqrt{s_{NN}}$ = 4.2 GeV is explored based on a relativistic transport model that is interweaved with hadronic mean-field potentials for heavy-ion collisions. Upon comparison, it appears that relative to the double strangeness observable $Ξ^-$, the yield and collective flows of the triple strange $Ω^-$ exhibit a higher sensitivity to the equation of state (EoS) of dense matter. This characteristic makes the $Ω^-$ an essential observable for studying the properties of densely formed matter in relativistic heavy-ion collisions. |
