Abstract：
In the framework of the resonating group method, the binding energies of double lambda hypernuclei ^6_ΛΛHe,^5_ΛΛHe,^5_ΛΛH,^4_ΛΛHe,and ^4_ΛΛH are calculated in the chiral SU(3) quark model. In the two-cluster approximation in which a two-lambda cluster and a core nuclei are considered, one finds that the resultant binding energy of double-lambda hypernuclei ^6_ΛΛHe is in good agreement with the experimental data. It means that the chiral SU(3) quark model can well-describe the spectrum of baryon, the interactions of N-N, Y-N, and the binding energies of light lambda hpernuclei, as well as the interaction of Y-Y and the binding energy of double-lambda hypernucleus. With the same set of parameters, we calculate the binding energies of light double-lambda hypernuclei ^6_ΛΛHe,^5_ΛΛHe,^5_ΛΛH,^4_ΛΛHe,and ^4_ΛΛH and discuss the possibilities of these states.
