Description
Many of the charmonium-like XYZ resonances observed by Belle, Babar, CLEO and BESIII collaborations in the past decade are difficult to interpret as conventional quark-antiquark mesons. After a brief review of the XYZ resonances, theoretical scenarios for these states will be presented with an emphasis on results from QCD sum-rule methods.
