摘要:
在夸克蜕定域色屏蔽模型框架下,利用共振群方法研究了同位旋为I=0和I=1,角动量为JP=1/2±,3/2±,5/2±的分子态ND体系,发现所有的正宇称态都不束缚. 经过多道耦合计算,我们得到了I=0,JP=1/2-的ND分子态,可以用来解释实验上报道的Σc(2 800),I=0,JP=3/2-的ND*分子态可以解释实验报道的Λc(2 940),另外还存在一个I=1,JP=5/2-的ΔD*分子态.
Abstract:
The ND systems with I=0 and I=1,JP=1/2±,3/2±,5/2± are dynamically investigated within the framework of the quark delocalization color screening model. The results show that by the channel-coupling calculation,there is a ND bound state with I=0,JP=1/2-,which can be used to explain the reported Σc(2 800); a ND* bound state with I=0,JP=3/2- is obtained,which can be used to explain the reported Λc(2 940). Besides,another bound state ΔD* with I=1,JP=5/2- is also obtained.
