Description
I review recent results on exotic hadrons such as glueballs and tetraquarks
obtained in the framework of functional Dyson-Schwinger and Bethe-Salpeter equations.
First results for quenched glueballs in this framework have been published in 2012; I
present an update of these results and discuss preliminary results in the unquenched case. For tetraquarks, based on our earlier results on the light scalar mesons we have generalized our approach to include heavy-light states with two charm and two light (anti-)quarks. I discuss results in the scalar and axialvector channel.
