Making Sense of the XYZ Mesons from QCD

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 may provide a framework for understanding the XYZ mesons.
