带有奇异夸克的双重子隐色道

The hidden color channel and strange dibaryon

在手征SU(3)夸克模型下讨论了如何在共振群方法下研究带有奇异夸克的双重子隐色道问题,详细给出了隐色道部分涉及的自旋空间、同位旋空间和颜色空间相互作用矩阵元的计算过程.此工作将有助于研究带有奇异夸克的双重子态的隐色道效应,从而深入认识带奇异夸克的多夸克结构.

In the present work we present a detailed method of calculating the matrix element of hid- den color channel in spin,isospin and color spaces in the chiral SU（3） quark model. It is the first time to extend the method from nonstrange dibaryon into strange dibaryon within the Resonating Group Method. This will be helpful to further study the effect from hidden color channel and understand the nature of multiquarrk state with strangeness.
