Description
We present results for the potential of two static anti-quarks in the presence of two light quarks. We improve on existing results the $\bar b \bar b u d$ tetraquark system by computing the static potential at off-axis separations, significantly increasing the number of data points in the crucial region of small distances. Moreover, we show entirely new results for the static potential of a $\bar b \bar b u s$ tetraquark. Finally, we discuss phenomenologically motivated parametrizations of the potentials.
