Abstract
In recent years, interest in charmonium spectroscopy has been renewed by the unexpected discovery of multiple states that seemingly do not fit a conventional CC¯ assigment. The BESIII experiment located at the BEPCII e+e− collider is at the forefront of investigations into these so-called XYZ states. With roughly 12 fb−1 of e+e− annihilation data above s=3.8 GeV, BESIII both has direct access to exotic states with JPC = 1−− (Y-states) and can study X- and Z-states through radiative or mesonic transitions. Within the presentation, recent contributions of the BESIII experiment to the ongoing studies of XYZ states were highlighted and an outlook into future perspectives with BESIII was given.
