The XYZ states: experimental and theoretical status and perspectives

N Brambilla, S Eidelman, C Hanhart, A Nefediev… - Physics reports, 2020 - Elsevier
The quark model was formulated in 1964 to classify mesons as bound states made of a
quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all …

Hadronic molecules in decays
