Title: Strange hadronic matter

In an extended mean field theory, there is found a large class of bound multi-strange objects, formed from combinations of (p,n,{Lambda} {Xi}{sup 0} {Xi}{sup {minus}}, baryons, which are stable against strong decay. A maximal binding energy per baryon of E{sub B}/A {approx} {minus}21 MeV, strangeness per baryon of {integral}{sub s} {approx} 1--1.2, charge per baryon of {integral}{sub q} {approx} {minus}-0.1 to 0.1, and baryon density of 2.5--3 times that of ordinary nuclei are predicted. For A {ge} 6, stable combinations involving only ({Lambda},{Xi}{sup 0},{Xi}) hyperons are obtained.
