Abstract
The non-Abelian nature of quantum chromodynamics predicts the existence of exotic states, such as glueballs, hybrids, and multiquarks states. The experimental confirmation of these states would provide fundamental information about QCD in the confinement regime and would be a direct test of the QCD theory. The radiative decays of charmonium are glue-rich processes and are considered to be excellent probes for the production of gluonic matter and light hadron structures. The BESIII experiment, which is in operation at the BEPCII electron-positron collider in Beijing since 2009, has collected world leading high statistic data samples in the charmonium region, this offers unique possibilities to study exotic QCD states in the charmonium sector.
