Strange hadronic matter

In an extended mean field theory, we find a large class of bound multistrange objects, formed from combinations of [l brace][ital p],[ital n],[Lambda],[Xi][sup 0],[Xi][sup [minus]][r brace] baryons, which are stable against strong decay. We predict a maximal binding energy per baryon of [ital E][sub...

Zusammenfassung:In an extended mean field theory, we find a large class of bound multistrange objects, formed from combinations of [l brace][ital p],[ital n],[Lambda],[Xi][sup 0],[Xi][sup [minus]][r brace] baryons, which are stable against strong decay. We predict a maximal binding energy per baryon of [ital E][sub [ital B]]/[ital A][approx][minus]21 MeV, strangeness per baryon [ital f][sub [ital s]][approx]1.2, charge per baryon [ital f][sub [ital q]][approx][minus]0.1 to 0, and baryon density 2.5--3 times that of ordinary nuclei. For [ital A][ge]6, we obtain stable combinations involving only [l brace][Lambda],[Xi][sup 0],[Xi][sup [minus]][r brace] hyperons.
