Abstract
The charmonium spectroscopy in the last decades has been enriched of a new family of particle states that could not be assigned to the conventional charmonium behavior. The study of those states, commonly named XYZ states, is an important task of the BESIII (BEijing Spectrometer III) research activities. BESIII looks at the collision results of electron and positron and it can produce directly states with quantum number JP C = 1−− and study their cross-section at different energies in order to understand the production mechanism of several final states. Moreover, the low hadronic background allows BESIII to measure precisely the transition of exotic states to conventional ones. Thanks to the large data set in the charmonium region, BESIII can determine the spin-parity of some of those states. In this paper, the current study of exotic XYZ states at BESIII will be presented.
