Description
A `second charm revolution' was sparked with the discovery of new
'XYZ' states, such as the $X(3872)$ or the $Y(4260)$ by the B factories
Belle and BABAR. These states do not fit into the conventional
picture of quark-antiquark bound systems. A number of further,
non-conventional bound states have been discovered in different
production processes at several experiments.
This talk will highlight several new states recently discovered at
BESIII, both in the light quark and the charmonium(-like) sector.
