Abstract:
It was computed the binding energy of one dihyperon H with the spin J=0 with the quark structure (uuddss) in the lattice QCD theory and it was find that this binding energy is B = 16.6 MeV [1].
In the bag model of the quarks interacting by exchange of gluons, considering the one gluon exchange, and the mass of the strange quark zero it was computed the mass of one dihyperon [1]. In the bag model were predicted two dihyperons, one with the mass 2150 MeV and the other with the mass of 2335 MeV [2].
In the present paper we present the mass formula applied in this model for the dihyperon [2].
We suppose that the mass of the strange quark of minimum 70 MeV [3] and the two or three gluon exchange between the quarks [4] are changing the mass of the dihyperon.
