Title: Properties of conventional and exotic hadrons from functional methods and application to (g-2)_mu

Abstract
In this talk I will give an overview on recent results on the spectrum and properties of conventional and exotic hadrons as well as applications to the (g-2)_mu as obtained in the framework of Dyson-Schwinger and Bethe-Salpeter equations. I will discuss the spectrum of light baryons with focus on the comparison with quark model expectations, the impact of dynamical mass generation and explain the importance of relativistic components in the wave functions of baryons. For four-quark systems I will summarize results for light quarks and discuss recent progress on discriminating between tetraquark, molecule or hadro-quarkonium configurations in heavy-light systems. I will also discuss the impact of the approach in the search for BSM physics by improving the theoretical determination of the anomalous magnetic moment of the muon, (g-2)_mu.
