The $X Y Z$ states: experimental and theoretical status and perspectives

Nora Brambilla, Simon Eidelman, Christoph Hanhart +5

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 know…

QCD sum rule studies on the $ss s ˉ s ˉ$ tetraquark states with $J^{P C} = 1^{+-}$

Er-Liang Cui, Hui-Min Yang, Hua-Xing Chen +2

We apply the method of QCD sum rules to study the structure $X$ newly observed by the BESIII Collaboration in the $ϕ η^{'}$ mass spectrum in 2.0-2.1 GeV region in the $J/ψ\righta…
