The Sub-Electron-Noise Skipper CCD Experimental Instrument (SENSEI) uses the recently developed Skipper-CCD technology to search for electron recoils from the interaction of sub-GeV dark matter particles with electrons in silicon. We report first results from a prototype SENSEI detector, which collected 0.019 g day of commissioning data above ground at Fermi National Accelerator Laboratory. These commissioning data are sufficient to set new direct-detection constraints for dark matter particles… Expand
SENSEI: Direct-Detection Constraints on Sub-GeV Dark Matter from a Shallow Underground Run Using a Prototype Skipper CCD.
World-leading constraints on dark matter-electron scattering for masses between 500 keV and 5 MeV, and on dark-photon dark matter being absorbed by electrons for a range of masses below 12.4 eV are derived. Expand
LBECA: A Low Background Electron Counting Apparatus for Sub-GeV Dark Matter Detection
Two-phase noble liquid detectors, with large target masses and effective background reduction, are currently leading the dark matter direct detection for WIMP masses above a few GeV. Due to theirExpand
Direct detection of strongly interacting sub-GeV dark matter via electron recoils
We consider direct-detection searches for sub-GeV dark matter via electron scatterings in the presence of large interactions between dark and ordinary matter. Scatterings both on electrons and nucleiExpand
Diamond detectors for direct detection of sub-GeV dark matter
We propose using high-purity lab-grown diamond crystal for the detection of sub–giga electron volt dark matter. Diamond targets can be sensitive to both nuclear and electron recoils from dark matterExpand

Exploring new physics with O(keV) electron recoils in direct detection experiments
Motivated by the recent XENON1T results, we explore various new physics models that can be discovered through searches for electron recoils in O $$ \mathcal{O} $$ (keV)-threshold direct-detectionExpand
Constraints on Dark Matter with a moderately large and velocity-dependent DM-nucleon cross-section
We derive constraints on a possible velocity-dependent DM-nucleon scattering cross section, for Dark Matter in the 10 MeV -- 100 GeV mass range, using the XQC, DAMIC, and CRESST 2017 Surface RunExpand
Migdal effect and photon bremsstrahlung in effective field theories of dark matter direct detection and coherent elastic neutrino-nucleus scattering
Dark matter direct detection experiments have limited sensitivity to light dark matter (below a few GeV), due to the challenges of lowering energy thresholds for the detection of nuclear recoil toExpand
Sources of Low-Energy Events in Low-Threshold Dark Matter Detectors
We discuss several low-energy backgrounds to sub-GeV dark matter searches, which arise from high-energy particles of cosmic or radioactive origin that interact with detector materials. We focus onExpand
Reverse direct detection: Cosmic ray scattering with light dark matter
Sub-GeV dark matter candidates are of increasing interest, because long-favored candidates such as GeV-scale WIMPs have not been detected. For low-mass dark matter, model-independent constraints areExpand


Direct detection of sub-GeV dark matter with semiconductor targets
