QCD sum rules approach to the X, Y and Z states

In the past decade, due to the experimental observation of many charmonium-like states, there has been a revival of hadron spectroscopy. In particular, the experimental observation of charged charmonium-like Zc states, and bottomonium-like Zb states, represents a challenge since they can not be acco...
