Decays of Pc into J/ψN and ηcN with heavy quark spin symmetry

We investigate the consequences of heavy quark spin symmetry (HQSS) on hidden-charm pentaquark Pc states. As has been proposed before, assuming the Pc(4440) and the Pc(4457) as S-wave D¯*Σc molecules, seven hadronic molecular states composed of D¯Σc, D¯Σc*, D¯*Σc, and D¯*Σc* can be obtained, with th...
