Description
We report on our lattice QCD computation of the static-light $\bar Q \bar Q qq$ potentials, using the CLS configurations and the OpenQ*D codebase. We utilize a set of 24 creation operators, corresponding to 12 sectors characterized by isospin, angular momentum and parity quantum numbers for $uu$, $ud$ or $dd$ light quarks and 6 sectors for $us$ or $ds$ light quarks. We include off-axis separations of the static antiquarks and use tree-level improvement. The resulting potentials provide some indication for one-pion exchange at intermediate $\bar Q \bar Q" separations.
