The CRESST-III Dark Matter Search: Status and Outlook — •Christian Strandhagen for the CRESST collaboration — Eberhard-Karls-Universität Tübingen, D-72076 Tübingen

The CRESST experiment (Cryogenic Rare Event Search with Superconducting Thermometers) operates an array of cryogenic detectors using different target materials in a well-shielded setup at the LNGS (Laboratori Nazionali del Gran Sasso) underground laboratory in Italy to search for nuclear recoils induced by scattering of dark matter particles in the detectors. With detection thresholds for nuclear recoils as low as 10 eV, CRESST is among the leading experiments in the search for low mass dark matter particles. The most recent measurement campaign, which started in summer 2020, was focused on investigating the origin of an unexplained event population at very low energies ("low energy excess") which is limiting the sensitivity of the experiment in the low mass region. We present the status of CRESST-III and report on observations of the low energy excess and dark matter results. Finally we show our plans for the coming years including the upgrade of the readout electronics.
