Abstract

The hadroquarkonium picture [S. Dubynskiy and M.B. Voloshin, Phys. Lett. B 666, 344 (2008)] provides one possible interpretation for the pentaquark candidates with hidden charm, recently reported by the LHCb Collaboration, as well as for some of the charmoniumlike "X, Y, Z" states. In this picture, a heavy quarkonium core resides within a light hadron giving rise to four-or five-quark/antiquark ...
