Abstract:

The ND systems with I=0 and I=1,J^P=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,J^P=1/2^-,which can be used to explain the reported Σ_c(2 800); a ND^* bound state with I=0,J^P=3/2^- is obtained,which can be used to explain the reported Λ_c(2 940). Besides,another bound state ΔD^* with I=1,J^P=5/2^- is also obtained.
