The Tensor Forces Effect On Y-N Interaction And Binding Energy Of Light Hypernuclei Base On The Chiral SU(3) Quark

The phenomenological interactions have frequently been employed as a general method in studying of Y ? Ninteractions, but it has so many free parameters. Although the calculations succeed in explaining some properties of some hypernucleis, it is impossible for it to agree with all the experimental data. A general model is always one of studying of hypernuclei.. Now, the theoretical studying in hypernuclei physics goes deep into the quark level from the bayon level with the development of particle physics. The research of near several dacades enunciated that the meson featured in the atomic nucleus phenomenons. In 1992, Fernandez et. gave quark-chiral interation based on the linear relation in σmodel. To study Y-N interation, Zhang et al. further expanded this model to chiral SU (3) quark model. In present paper, we add tensor force of VOGE (odd-gluon tensor force for short) and add tensor force of Vch (chiral tensor force for short) in the interaction of quark-quark based on the chiral SU (3) quark model. We study the change of the Hamiltonian of the quark system in Lambda-proton cross section. With this Hamiltonian we calculate the non-local potential of Λ-N interaction, as well as binding energies of some light hypernucleis. We also individually study the effects of the chira tensor force and the odd-gluon exchange tensor force on the binding energies of light hypernucleis. The result shows that the tensor force has little effect on Lambda-proton cross section; the non-local potential of Λ-N interaction with tensor force and central force is different from the non-local potential of Λ-N interaction with central force in the rang of middling and long distances, and this difference lead to more changes in the binding energies of light hypernucleis. Commonly we think that the effect of tensor forces on light hypernucleis is minor, and all the tensor forces lead to the results which accord with the non-local potential of Λ-N interaction. Because the chira tensor force is repulsive potential, it makes the binding energys of light hypernucleis become small. And the odd-gluon exchange tensor forces is attrahent potential, it makes the binding energy of light hypernucleis become great. By the way, from the results and the figures, we know that the chira tensor force is the central part of the tensor forces. In a word, applying the chiral SU (3) quark model to the research of light hypernucleis will be positivet, not only for the development of the research of hypernuclear physics but also for the more consummate of the model itself.
