Description

The hidden charm pentaquark states Pc(4312), Pc(4440), and Pc(4457) can be well assigned as \barD^(*)Sigma_c molecules, which are related by heavy quark spin symmetry. To further study the pentaquark states in the molecular picture, we have taken the heavy quark diquark symmetry to predict the Xicc Sigmac and barD T_cc molecules. Such kind of molecules belong to new molecule that are not discovered by experiment so far. If they were discovered, it will verified the molecular nature of pentaquark states. In addtion, we have predicted the hidden charm pentaquark states decaying into three-body final states in the molecular picture, which are also helpful to understand the molecular nature of pentaquark states.
