Description
We have used standard numerical techniques of lattice quantum chromodynamics to look for evidence of the proposed doubly strange spin-zero dibaryon (the H particle), and to determine the splitting between the mass of the H and the mass of two Λ's, its lightest possible strong-decay channel. We find that the dibaryon is above the two-Λ threshold, making it unstable to strong decay
