Ratios of Hidden-Charm Compact Pentaquark Decay Widths in Quark-Diquark Model

A number of resonances comparable with a hypothesis of hidden-charm pentaquark is observed by the LHCb Collaboration. We interpret these narrow resonances as compact hidden-charm diquark-diquark-antiquark systems. Within this assumption, an interplay between the charmonium and open-charm modes is co...

Description
Summary:	A number of resonances comparable with a hypothesis of hidden-charm pentaquark is observed by the LHCb Collaboration. We interpret these narrow resonances as compact hidden-charm diquark-diquark-antiquark systems. Within this assumption, an interplay between the charmonium and open-charm modes is considered. Ratios of such modes for non-strange pentaquarks are obtained and discussed.
