摘要:
本文在手征夸克模型和夸克蜕定域色屏蔽模型框架下,利用共振群方法研究了角动量J=0和J=1的p(-overΛ)体系,发现在这两个模型中p(-overΛ)都不是一个束缚态,但在夸克蜕定域色屏蔽模型中,我们在p(-overΛ)散射过程中发现了一个IJ=1/20的p(-overΣ)共振态.
Abstract:
The p(-overΛ) systems with J=0 and J=1 are dynamically investigated within the framework of two constituent quark models:the chiral quark model and the quark delocalization color screening model.The results show that,there is no p(-overΛ) bound state in both two models.However,the p(-overΛ) elastic scattering processes with coupling to p(-overΣ) state are studied and a IJ=1/20 p(-overΣ) resonance state is given in the quark delocalization color screening model.
