The DAMIC-M (DArk Matter In CCDs at Modane) experiment will use skipper CCDs to search for low mass (sub-GeV) dark matter underground at the Laboratoire Souterrain de Modane (LSM). With about 1kg of silicon target mass and sub-electron energy resolution, the detector will surpass the exposure and threshold (eV-scale) of previous experiments. As such, DAMIC-M will have world-leading sensitivity...
PADME is a fixed-target, missing-mass experiment originally designed to search for dark photons using a beam of positrons with energy up to 500 MeV. The detector, located at the Laboratori Nazionali di Frascati, in Italy, has already collected initial physics data over the last few years. More recently, the experiment has been adapted to perform a direct search for on-shell X17 production....
DarkSide-LowMass is a tonne-scale liquid argon time projection chamber (LArTPC) being planned by the Global Argon Dark Matter Collaboration (GADMC) to search for WIMP-like dark matter with masses below 10 GeV/c^2, achieving low thresholds with a design optimized for an electron-counting analysis. Building upon the success of DarkSide-50's light dark matter search, DarkSide-LowMass will aim to...
The XENONnT experiment searches for weakly interacting massive particles scattering off xenon nuclei with a dual-phase time projection chamber. With 5.9 tonnes of active mass and an unprecedented low level of background, the detector enables the searches of several rare-event physics channels. In particular XENONnT set stringent limits on other dark matter candidates interacting through...
TESSERACT is currently in an R&D and planning phase, funded under the DOE Dark Matter New Initiatives program. This phase will result in two fully defined experiments (HeRALD and SPICE). Collaboration with French groups has recently been formalized, bringing a third technology to the suite. We will provide an overview of this general TESSERACT program as we transition to `project’ phase. In...
SENSEI (Sub-Electron Noise Skipper Experimental Instrument) is the first experiment to implement silicon skipper CCDs to search for dark matter. Skipper-CCDs can resolve single electrons in each of millions of pixels, which allows for the low energy threshold required to detect sub-GeV dark matter interacting with electrons. SENSEI recently measured the lowest event rates containing one...
