### Speaker

Marc Wagner (Goethe University Frankfurt)

### Description

We present first results of a recently started lattice QCD investigation of antiheavy-antiheavy-light-light tetraquark systems including scattering interpolating operators in correlation functions both at the source and at the sink. In particular, we discuss the importance of such scattering interpolating operators for a precise computation of the low-lying energy levels in $\bar b \bar b u d$ and $\bar b \bar b u s$ four-quark systems and corresponding scattering analyses.
