Description
Since Pc(4380) and Pc(4450) were discovered by LHCb collaboration in 2015, the nature of two pentaquarks is still veiled. Recently, three pentaquark states, Pc(4312), Pc(4440),
Pc(4457) were discovered by LHCb with more precision, which inspired us to explore the nature of three pc states. In this talk, I will discuss the implementation of effective field theory to describe the three pentaquark states Pc(4312), Pc(4440),
Pc(4457) in terms of molecular picture, and also compared our results with one boson exchange model to analysis the issue of spin of Pc(4440) and Pc(4457), besides a series of molecular states emerged in a complete heavy-quark spin symmetry multiplet of charmed mesons and baryons are also presented.
