Strange hadronic matter

In an extended mean field theory, we find a large class of bound multistrange objects, formed from combinations of {p,n,\ensuremath{\Lambda},${\mathrm{\ensuremath{\Xi}}}^{0}$,${\mathrm{\ensuremath{\Xi}}}^{\mathrm{\ensuremath{-}}}$} baryons, which are stable against strong decay. We predict a maximal binding energy per baryon of ${\mathit{E}}_{\mathit{B}}$/A\ensuremath{\approxeq}-21 MeV, strangeness per baryon ${\mathit{f}}_{\mathit{s}}$\ensuremath{\approxeq}1.2, charge per baryon ${\mathit{f}}_{\mathit{q}}$\ensuremath{\approxeq}-0.1 to 0, and baryon density 2.5--3 times that of ordinary nuclei. For A\ensuremath{\ge}6, we obtain stable combinations involving only {\ensuremath{\Lambda},${\mathrm{\ensuremath{\Xi}}}^{0}$,${\mathrm{\ensuremath{\Xi}}}^{\mathrm{\ensuremath{-}}}$} hyperons.
