| 英文摘要 | The study of hypernuclei in the quark mean-field model are extended from single-Lambda hypernuclei to double-Lambda hypernuclei as well as Xi hypernuclei (double strangeness nuclei), with a broken SU(3) symmetry for the quark confinement potential. The strength of the potential for u, d quarks is constrained by the properties of finite nuclei, while that for the s quark is fixed by the single Lambda-nucleus potential at the nuclear saturation density, which has a slightly different value. Compared to our previous work, we find that the introduction of such symmetry breaking improves efficiently the description of the single-Lambda energies for a wide range of mass regions, which demonstrates the importance of this effect on the study of hypernuclei. Predictions for double-Lambda hypernuclei and Xi hypernuclei are then made, and compared with some of the available experiential double-Lambda hypernuclei data and other model calculations. The consistency of our results with the available double-Lambda hypernucleus is found to be surprisingly good. Also, there is generally a bound state for Xi(0) hypernuclei with both light and heavy core nuclei in our model. |
