Description
Since the discovery of tetraquarks, there has been a lot of excitement around this topic from the
theoretical as well as the experimental side. To study the poperties of these four-quark states we
use a functional framework which combines (truncated) Dyson-Schwinger and Bethe-Salpeter
equations in Landau gauge. This approach allows us to extract qualitative results for mass spectra,
decay widths and wavefunctions of tetraquark candidates. Furthermore, we can investigate the
possible internal structure of such states. We report on recent developments and results using this
functional framework and give an overview about the current status as well as future developments.
