Description

Abstract:

The quarkonium spectrum is well understood below the open-flavour threshold. Above threshold, however, experiments have found a large number of new, potentially exotic hadrons that do not always match our expectations for regular quarkoonium hadrons - the XYZ states. Experiments like BESIII, using 𝑒+𝑒− annihilation to produce pairs of heavy quarks, are particularly well suited to study the vector quarkonia. In this talk, I will discuss recent measurements of open- and hidden-flavour production above threshold, as well as a path towards a common interpretation of that data using a coupled-channel approach.
