Experimental and theoretical status of and perspectives for XYZ states

While a majority of the community agrees that the XYZ states have a non-q̄q nature, the internal structure of these states is not yet understood. To deepen our understanding in this field, additional experimental and theoretical studies are needed. For example, complete spin multiplets should be studied; to distinguish true resonance signals from kinematic effects, the confirmation of states in different experiments is needed; resonance shape measurements are compulsory to access the long ranged parts of the exotic wave functions.
At present most experimental information comes from Belle (II) (Japan), BESIII (China) and LHCb (CERN). The gluon-rich process of pp̄ annihilation as it will be available for the upcoming PANDA experiment at the FAIR facility (Germany) promises new and complementary insights. The workshop focusses on the status and future perspectives in the field of exotic hadrons in the heavy quarkonium mass region.
