讲座摘要:Inspired by the observations of the pentaquark-like states found by LHCb, we investigated these heavy pentaquark states with the coupled channel unitary approach, taking into account the heavy quark spin symmetry and local hidden gauge symmetry. We dynamically reproduced three Pc states and Pcs(4459) in the interactions of the channels Dbar*-c* and Dbar*-Xic* with their coupled channels, respectively. Furthermore, we also show the results on the two-poles structure of the Λ(1405) state in the interactions of KbarN and π∑ with their coupled channels. Thus, one concluded that these resonances were molecular states.
