Exploring Sub-GeV Dark Matter with CRESST: Advances, Challenges, and Prospects — •Marco Maria Zanirato — Max Planck Institut für Physik, München, Deutschland

The Cryogenic Rare Event Search with Superconducting Thermometers (CRESST) is a forefront experiment in the direct detection of dark matter, operating at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. Utilising cryogenic calorimeters based on (mainly) scintillating crystals equipped with Transition Edge Sensors (TESs), CRESST achieves exceptional energy thresholds on the order of 30eV and operates at temperatures in the millikelvin range. These capabilities make CRESST uniquely suited to probe dark matter particles with sub-GeV masses. This talk will provide a comprehensive overview of CRESST, highlighting the working principles of its detectors, the latest results in dark matter searches, and the challenges inherent to such a cutting-edge experiment. The discussion will also include insights into ongoing efforts to refine detector designs and enhance the experiment's sensitivity, paving the way for future explorations in the quest to discover the nature of dark matter.
