Abstract

The mass of the lowest spin-zero, strangeness-(2)(-2) flavor singlet state in the dibaryon sector has been calculated in quenched QCD on 163×3216^3\times32 and 243×3224^3\times32 lattices at β=5.85\beta=5.85 to study whether the energy of the proposed HH dibaryon is near or below the ΛΛ\Lambda\Lambda threshold. Preliminary results indicate that finite lattice volume artifacts overestimate the binding, and that on the largest lattice mHm_H is of the order of 100\MeV100\MeV above the ΛΛ\Lambda\Lambda threshold.
