在手征SU （3）夸克模型和推广SU （3）手征夸克模型下，应用共振群方法研究了奇异数为-5的双重子系统的结构，主要分析了标量介子混合角对系统结合能的影响。结果表明，无论是哪种混合，双重子Ξ*Ω都是束缚态。在手征夸克模型下，混合角为-18°和19°时，Ξ*Ω系统结合能大致相同；但在理想混合下，因为σ场没有贡献，系统的结合能会大大减少。同时还发现，考虑混合角时的结合能远小于不考虑混合角时的结合能。本文工作对标量介子混合角问题的研究提供了一些有意义的信息。

In the chiral SU (3) quark model and extended chiral SU (3) quark model ,we study the structure of strangeness -5 dibaryon by solving a Resonating Group Method equation .The effects from the mixing of scalar mesons are analyzed in the chiral SU (3) quark model ,the binding energies are almost the same for -18°and 19°mixing cases .But the binding energy is reduced quite a lot for i-deal mixing case ,since there is no contribution from σmeson .Compared with the results of no mixing case ,the binding energies are reduced a lot for any ming cases .The present work might be helpful in understanding the question of mixing of scalar mesons .
