H-dihyperon in quark cluster model

The H-dihyperon (DH) is studied in the framework of the SU(3) chiral quark model. It is shown that, with the exception of the sigma chiral field, the overall effect of the other SU(3) chiral fields is destructive in forming a stable DH. The resultant mass of DH in a three-coupled channel calculation ranges from 2225-2234 MeV.
