摘要
在共振群框架下用组分夸克模型研究了奇异数为s=-3的六夸克系统的束缚能 .分别考虑了自旋S =2的单道NΩ和自旋S =3的单道ΔΩ .结果显示两个系统都可以形成松散的束缚态 :NΩ的束缚能为 3 .5到 1 2 .7MeV ,而ΔΩ的束缚能为 4 .4到 1 4.2MeV .
We investigate the binding energy of six quark systems with strangeness s =-3 under the constituent quark model in the framework of RGM. The single NΩ channel with spin S= 2 and the single ΔΩ channel with spin S= 3 are considered, respectively. The results show that both two systems can form loosely bound states: the binding energies are ranged from 3.5—12.7 MeV for NΩ and 4.4—14.2 MeV for ΔΩ system, respectively.
