The XYZ mesons are unexpected mesons containing a heavy quark and antiquark that have been discovered in the last decade.  Their number has grown to about  two dozen.  Many of them are surprisingly narrow, and several are electrically-charged  tetraquark mesons.  Their existence presents a serious challenge to our understanding  of the spectrum of QCD.   I will explain how the Born-Oppenheimer approximation  can be used to begin to understand the XYZ mesons.
