Antistatic-antistatic-light-light potentials from lattice QCD

We present results for tetraquark potentials of two static anti-quarks $\bar{b}\bar{b}$ in the presence of two light quarks $u$ and/or $d$. We improve on existing results by computing the static potential also for off-axis separations, which increases the number of data points significantly. Moreover, we compute for the first time $\bar{b}\bar{b}us$ potentials.
