Description
The BESIII Experiment at the Beijing Electron Positron
Collider (BEPC2) collected large data samples for electron-positron
collisions with center-of-mass above 4 GeV during 2013 and 2014. The
analysis of these samples has resulted in a number of surprising
discoveries, such as the discoveries of the electrically charged "Zc"
structures, which, if resonant, cannot be accomodated in the
traditional charm quark and anti-charm quark picture of charmonium.
In this talk, we will review the current status of the analyses of the
Zc structures, as well as a number of other interesting features in
the new BESIII data samples.
