Earth-Scattering Induced Modulation in Low-Threshold Dark Matter Experiments
Xavier Bertou, Ansh Desai, Timon Emken +3
Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth before reaching and scattering in a detector. This induces a modulation in…

Light(ly)-coupled Dark Matter in the keV Range: Freeze-In and Constraints
Jae Hyeok Chang, Rouven Essig, Annika Reinert
Dark matter produced from thermal freeze-out is typically restricted to have masses above roughly 1 MeV. However, if the couplings are small, the freeze-in mechanism allows for pro…

SENSEI: First Direct-Detection Results on sub-GeV Dark Matter from SENSEI at SNOLAB
SENSEI Collaboration, Prakruth Adari, Itay M. Bloch +34
We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximat…
