]]>Dark matter particles significantly lighter than in the paradigmatic WIMP scenario are increasingly considered to be phenomenologically viable. Detecting these particles requires new experiment strategies. The paper proposes that experiments based on certain superconducting targets could detect ultralight dark matter particles with masses in the meV-eV range.

We recast the ATLAS standard model $t\overline{t}Z$ measurement to put limits on the rate for this process. Limits are also set on the two Higgs doublet model at low $\mathrm{tan}\beta $ …
