Description
In recent years, a number of charmonium-like states have been observed
above the open-charm threshold in various experiments. Their properties often go
against our expectations for regular charmonium states, making their
interpretation difficult. With BESIII, we are a leading contributor to the
experimental studies of the so-called XYZ states – studying Y-states directly in
e+e- annihilation, while producing X and Z states in hadronic and radiative
transitions. In this talk, recent highlights from the BESIII program on
charmonium(-like) states above the open-charm threshold will be discussed.
