Light baryon spectroscopy

Light baryon spectroscopy, photoproduction


One of the unresolved questions in Hadron Physics comes from the field of Baryon Spectroscopy. Here, the exact interaction between the quarks inside the nucleons is investigated via measurement of the excitation spectrum of the nucleons. Comparison to constituent quark models as well as lattice QCD calculations reveal substantial differences is the number of observed states and in the mass hierarchy of the first excitations. This proceeding will give a short recap about the current developments in the field of Light Baryon Spectroscopy.
