Description

We search for possibly existent bound states in the heavy-light tetraquark channels with quark content $\overline{b}\overline{b}ud$, $\overline{b}\overline{b}us$ and $\overline{b}\overline{c}ud$ using lattice NRQCD for the heavy quarks. We use different gauge link ensembles with $N_f=2+1$ flavours of domain-wall fermions and consider a basis of local and non-local interpolators. Besides extracting the energy spectrum from the correlation matrix, we perform additionally a Lüscher analysis to extrapolate our results to infinite volume.
