Description
The BESIII Experiment is dedicated to studying electron-positron collisions in the charmonium region. In recent years, the BESIII Collaboration has used the accelerator and detector to explore the spectrum of excited charmonium states, often dubbed *XYZ* states. Large samples of data have been collected with e+e- collision energies at or near the masses of the *Y*(4260) and *Y*(4360) states. These data have produced several exciting results including the observation of two charged charmonium-like states with masses near 4 GeV. Due to the fact that these states have electric charge, they cannot be simple charm anti-charm quark mesons. A discussion of these results and other recent, related results from the BESIII Experiment will be presented.
