The Projected Sensitivity of the DELight Experiment — •Eleanor Fascione for the DELight collaboration — Kirchhoff-Institut für Physik
In the search for dark matter, there is vast unexplored parameter space for masses below a few GeV, and the field of direct dark matter detection is constantly expanding to new frontiers. Low mass dark matter candidates necessitate novel detector designs with lower thresholds and alternative target materials compared to experiments currently providing the strongest overall constraints on many thermal dark matter models. The Direct search Experiment for Light dark matter (DELight) will deploy a target of superfluid 4He instrumented with large area microcalorimeters (LAMCALs) based on magnetic microcalorimeter (MMC) technology in a setup optimized for light dark matter searches. In this talk an overview of this upcoming experiment will be presented along with the expected dark matter sensitivity.
