Perhaps a Stable Dihyperon

R. L. Jaffe
1977 Physical Review Letters  
In the quark bag model the same gluon exchange forces which. make the proton lighter than the 41236) bind 6 quarks to form a stable,flavor singlet (strangeness -2) JP = O+ dihyperon (H) at 2150 MeV. Another isosinglet dihyperon (H*) with JP = l+ at 2335 MeV should appear as a bump in AA invariant mass plots. Production and decay systematics of the H are discussed. $ubmitted to Physical Review Letters)
