Molecular nature of Pcs(4459) and its heavy quark spin partners

Inspired by the observation of the Pcs(4459) state by LHCb recently, we reexamine the results of the interaction of the J/ψΛ channel with its coupled channels, exploiting the coupled channel unitary approach combined with heavy quark spin and local hidden gauge symmetries. By tuning the only free pa...
