Published online: 29 May 2015
In this contribution we review recent results from the BESIII experiment. We focus on the investigation of XYZ states and the discovery of new charged charmonium - like structures. Two isospin triplets Z(3900) and Z(4020) have been discovered, decaying into π± J/ψ and π± hc, respectively. Structures with compatible parameters have been found decaying to DD̄∗ and D∗D̄∗, respectively, suggesting that these structures might be of the same origin. Furthermore, we have investigated the transition Y(4260) → γX(3872). This is the first observation of a radiative transition between XYZ states.
