Further evidence for an unstable H-dibaryon?

We present preliminary results for the mass of the 6q flavor-singlet state ( J P = 0 +, S = −2) called H-dibaryon, calculated in quenched QCD on 16 3×30 and 24 3×30 lattices with improved gauge and fermion actions (Symanzik improvement, Clover action). For both lattice sizes we applied the fuzzing t...

Description
Summary:We present preliminary results for the mass of the 6q flavor-singlet state ( J P = 0 +, S = −2) called H-dibaryon, calculated in quenched QCD on 16 3×30 and 24 3×30 lattices with improved gauge and fermion actions (Symanzik improvement, Clover action). For both lattice sizes we applied the fuzzing technique to enhance the overlap with the ground state. We observe a H-mass above the ΛΛ-threshold for strong decay. The difference in mass, m H − 2 m Λ , increases with increasing lattice size.
