| Abstract: | We investigate the structure of H particle within the framework of chiral SU（3） quark mod- el and the extended chiral SU（3） quark model. Firstly,the different mechanisms of short--range in- teractions,vector exchange or one-gluon exchange, are analyzed. Secondly, the different confinement potentials and channel-coupling effects are studied. Finally,the effects of the mixing of scalar mesons on the H particle are investigated. The results show that the further exact information from experi- ments will be helpful in deciding the different confinement potentials and the mixing of scalar mesons in our models. |
