摘要
运用ＳＵ（３）手征夸克模型，系统地研究了Ｈ，ｄ＊和ｄ＇三个六夸克体系的结构，分析了ＳＵ（３）手征场和矢量耦合禁闭势等非微扰效应对三种六夸克态能量的影响。结果发现，ＳＵ（２）手征场的耦合，对形成六夸克态是有利的，但是扩大到ＳＵ／（３）手征对称，则由于这些手征场的“云”，对六夸克系统形成束缚的双重子态起到了限制的作用，矢量耦合禁闭势有利于Ｈ的形成，而对ｄ＊则相反。
The SU(3) chiral quark model is used to invesdgate the structures of three six-quark systems-H dibaryon d' and d' states. The non-perturbative QCD effects such as SU(3) chairl field coupling and the vector-coupling effect on the confinement potential are studied. The results show that the .(2) chiral field coupling makes six-quark system more stable, but the SU(3) chiral'cloud' is not favourable to form the dibaryons
