Constraints on Sub-MeV Dark Matter from Solar Reflection with DAMIC-M

K. Aggarwal, I. Arnquist, N. Avalos +41

The Sun acts as a natural dark matter accelerator. Galactic halo particles scattering in the solar plasma emerge with velocities well beyond the Galactic escape speed, providing a…

When direct detection constrains reheating temperature: freeze-in with stronger couplings and inflaton-seeded freeze-in

Xavier Bertou, Olivier Deligny, Mathieu Gross +2

Recent results from the DAMIC-M and PandaX collaborations have excluded the standard freeze-in production of dark matter for masses in the range $3~\mathrm{MeV} \lesssim m_χ\lesss…

Searches for CEνNS and Physics beyond the Standard Model using Skipper-CCDs at CONNIE

Alexis A. Aguilar-Arevalo, Nicolas Avalos, Xavier Bertou +31

The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) aims to detect the coherent scattering (CENS) of reactor antineutrinos off silicon nuclei using thick fully-deplet…

Daily Modulation Constraints on Light Dark Matter with DAMIC-M

K. Aggarwal, I. Arnquist, N. Avalos +40

The flux of Hidden Sector particles from the Galactic halo reaching an underground detector can be significantly attenuated by interactions within the Earth for sufficiently large…

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…

SENSEI: A Search for Diurnal Modulation in sub-GeV Dark Matter Scattering

Itay M. Bloch, Ana M. Botti, Mariano Cababie +28

Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth's atmosphere and crust before reaching an underground detector. This Earth-…
