Further evidence for an unstable H dibaryon?

x30 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

\Lambda\Lambda

threshold for strong decay. The difference in mass,

m_H - 2m_\Lambda

, increases with increasing lattice size.
