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