Testing the χc1p composite nature of the Pc(4450)
Making use of a recently proposed formalism, we analyze the composite nature of the Pc(4450) resonance observed by LHCb. We show that the present data suggest that this state is almost entirely made of a χc1 and a proton, due to the close proximity to this threshold. This also suppresses the decay m...
