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.
