Spectra and properties of conventional and exotic hadrons from functional methods

We summarise recent theoretical results on the spectrum and properties of zero, two, three- and four-quark states obtained from functional QCD using Dyson-Schwinger and Bethe-Salpeter equations. We discuss properties of glueballs in Yang-Mills theory and prospects to study their properties in QCD. We discuss differences and similarities in the spectra of light and strange baryons and address the flavour dependence and the internal structure of four-quark states with open and hidden charm and bottom content.
