摘      要：The structure of H dihyperon(DH)is investigated by employing the SU(3)chiral quark *** the structure of DH,two different conHguations,six-quark cluster configuration and two-cluster configuration,are considered,*** result shows that except the a chiral Held,the overall effect of the other SU(3)chiral fields is destructive in forming a stable DH and the two-cluster configuration is the preferred *** resultant mass of DH in a three-coupled-channel calculation in the SU(3)chiral quark model is ranged from 2225 to 2234 MeV.
