Laboratories of the Strong Interaction: Exotic Hadrons — •Sebastian Neubert — Physikalisches Institut, Heidelberg, Germany

The formation of hadrons, which escape description through the quark model, is a most fascinating effect of the strong interaction. Such exotic hadrons can be studied with a variety of experimental techniques. The discovery of mesons composed of four quarks in decays involving charmonia at the B-factories has opened an experimental window that is especially well suited to the direct observation of effects beyond the quark model. With the discovery of Pentaquark candidates in their decay to J/ψ proton, LHCb has extended this window to the baryon sector. These phenomena are unique laboratories to study multiquark and multihadron effects in the spectrum of QCD, which may hold the key to some of the oldest questions in understanding the strong interaction.
