Description
Constituting the largest fraction of all multiquark states observed by experiment, tetraquark mesons carrying overall quark flavour quantum numbers identical to those of conventional quark–antiquark mesons necessitate their particularly careful phenomenological treatment. A collection of (more or less recent) insights specific to the latter subset of exotic hadrons promises to enable significant improvements in the understanding of these states by theoretical approaches such as, for instance, the formalism of QCD sum rules.
