Probing the strong interaction in e+e- collisions

The theory of the strong interaction, Quantum Chromodynamics, has been
probed very successfully up to very high energies, for example using
hadron production in electron-positron collisions. At low energy
scales, the QCD potential is non-perturbative and still not fully
One approach to obtain deeper insight into the non-perturbative regime
of the strong interaction is the study of charmonium spectroscopy.
e+e- annihilation provides a very clean environment A `second charm
revolution' has been sparked with the discovery of states such as the
X(3872) or the Y(4260) by the B factories Belle and BABAR, which do
not fit into the conventional picture of quark-antiquark bound
systems. In this talk, I will concentrate on some of the more exotic
bound states recently discovered at BESIII.
