Description

The XYZ mesons are unexpected mesons discovered in the last decade that contain a heavy quark and antiquark but have properties that suggest they also have additional constituents. Many of them are surprisingly narrow, and several are definitely 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 within QCD.
