In the quark bag model, the same gluon-exchange forces which make the proton lighter than the (1236) bind six quarks to form a stable, flavor-singlet (with strangeness of - 2) J^P=0^+ dihyperon (H) at 2150 MeV. Another isosinglet dihyperon (H^*) with J^P=1^+ at 2335 MeV should appear as a bump in invariant-mass plots. Production and decay systematics of the H are discussed.
R. L. Jaffe (1977) studied this question.
