Antistatic-antistatic-light-light potentials from lattice QCD

We present results for tetraquark potentials of two static anti-quarks b̅b̅ 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 b̅b̅ u s potentials.
