H-Dibaryon from Lattice QCD with Improved Anisotropic Actions
The six quark state(uuddss) called H dibaryon(,) has been
calculated to study its existence and stability. The simulations are performed
in quenched QCD on and anisotropic lattices
with Symanzik improved gauge action and Clover fermion action. The gauge
coupling is and aspect ratio . Preliminary results
indicate that mass of H dibaryon is 2134(100)Mev on lattice and
2167(59)Mev on respectively. It seems that the radius of H
dibaryon is very large and the finite size effect is very obvious
