Diquark Approach to Calculating the Mass and Stability of H-Dibaryon

Diquarks may play an important role in hadronic physics particularly near the phase transitions ( chiral , deconfinement points ), current lattice QCD determinations of baryon charge distributions do not support the concept of substantial u - d scalar diquark clustering as an appropriate description of the internal structure of nucleon. Thus vector diquarks are more favourable. By using of vector diquark ideas in the chiral limit diquark correlations in the relativistic region and imposing HF interactions between quarks in a vector diquark we calculated the mass of Hdibaryon, also by using of tunneling method we simultaneously calculated its decay width.
