Description
In this talk I will give a general overview on recent results from several groups
on the spectrum and properties of three- and four-quark states 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 summarise results for light quarks and discuss
the prospects of the approach to discriminate between tetraquark, molecule or
hadro-quarkonium configurations in heavy-light states.
