Abstract

The EDELWEISS direct detection experiment uses cryogenic Ge semiconductor detectors to search for sub-GeV dark matter (DM) particles. With its low gap energy, germanium is an excellent target to explore DM particles interactions with nucleons in the sub-GeV range, and DM-electron interactions in the MeV range, as well as search for the absorption of eV-scale dark photons. The collaboration has recently obtained the first Ge-based constraints on sub-MeV dark DM particles interacting with electrons using a 33.4 g Ge cryogenic detector prototype with a 0.53 electron-hole pair (rms) resolution, operated underground at the Laboratoire Souterrain de Modane.
These results will be presented, as well as the EDELWEISS-SubGeV plans to achieve lower threshold and more efficient particle identification at low energy.
