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 …

A review of the open charm and open bottom systems
Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom
hadrons were observed. In 2003 two narrow charm-strange states $ D_ {s0}^{\ast}(2317) …
