The hidden-charm pentaquark and tetraquark states

In the past decade many charmonium-like states were observed experimentally. Especially those charged charmoniumlike Z c states and bottomonium-like Z b states can not be accommodated within the naive quark model. These charged Z c states are good candidates of either the hidden-charm tetraquark states or molecules composed of a pair of charmed mesons. Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model. In this work, we review the current experimental progress and investigate various theoretical interpretations of these candidates of the multiquark states. We list the puzzles and theoretical challenges of these models when confronted with the experimental data. We also discuss possible future measurements which may distinguish the theoretical schemes on the underlying structures of the hidden-charm multiquark states.

Zusammenfassung Die starke Wechselwirkung im niederenergetischen Bereich, die sich in der Formation von gebundenen Teilchen darstellt, ist um neue Facetten reicher geworden. Experimente haben Evidenz für Teilchen aus Vier‐ und Fünf‐Quarkzuständen gefunden, die aufgrund ihrer ungewöhnlichen Eigenschaften nicht in das etablierte Baryonen‐ oder Mesonenschema passen. Ihre detaillierte Untersuchung wird unser Wissen über Hadronen, die aus Quarks und Gluonen aufgebaut sind, und deren Wechselwirkung um neue Kapitel erweitern.
