Study Of Σ And Ξ Hypernuclei Based On The Chiral SU(3) Quark Model

It is general to adopt the way of model to study the nonpertubative QCD behavior. With developing of particle physics, the theoretical studying hypernuclear physics go deep into the quark level from the bayon Level. As a model with QCD inspirit, the constituent quark model(CQM)is turned out to be quite successful in researching the N-N interaction but there are some questions such as not answering how is the source of the constituent quark mass in this model. Subsequently, people acquire gradually that restoring the chiral symmetry in the lagrangian is an important symmetry of the quark-chiral interaction and can resolve some of these problems. In 1992, Fernandez et. gave quark-chiral interaction based on the linear relation inσmodel and consequently improve the calculated N-N scattering result. To study Y-N interaction, Zhang et al further expanded this modal to chiral SU(3)quark modal. With an unified set of model parameters, they obtained results with reasonably explained the partial ground properties of single bayon and agreed with the experimental N-N scattering phase shift and Y-N scattering cross sections. It is so successful to explain N-N,Y-N and Y-Y interaction in this way that there has a new situation in theory.To check the rationality of the SU(3) quark model further as well as studyΣandΞcharacter primarily , theΣ-ΝandΞ-Νinteraction and the ground binding energy of correlative hypernucleur are researched based on SU(3)quark model in this paper. my main work is: firstly, using the GCM method ,I calculate the nonlocal potential ofΣ-ΝandΞ-Νinteraction in SU(3) quark model. secondly, the light hypernuclei is assumed to have the two groups structure of a nuclear core plus a Y particle. then by employing the GCM method and Kohn-Hulthen-Kato variation ,I calculateΣ4 He,Σ3 He and the group binding energies of some hypernucluei withΞ.
