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…
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…
First Production of Skipper-CCD Modules for the DAMIC-M Experiment
H. Lin, M. Traina, S. Paul +65
The DAMIC-M experiment will search for sub-GeV dark matter particles with a large array of silicon skipper charge-coupled devices (CCDs) at the Modane Underground Laboratory (LSM)…
Probing Benchmark Models of Hidden-Sector Dark Matter with DAMIC-M
M Collaboration, K. Aggarwal, I. Arnquist +39
We report on a search for sub-GeV dark matter (DM) particles interacting with electrons using the DAMIC-M prototype detector at the Modane Underground Laboratory. The data feature…
Search for Light Dark Matter with NEWS-G at the Laboratoire Souterrain de Modane Using a Methane Target
M. M. Arora, L. Balogh, C. Beaufort +40
The NEWS-G direct detection experiment uses spherical proportional counters to search for light dark matter candidates. New results from a 10 day physics run with a $135\,\mathrm{c…
The ionization yield in a methane-filled spherical proportional counter
M. M. Arora, L. Balogh, C. Beaufort +40
Spherical proportional counters (SPCs) are gaseous particle detectors sensitive to single ionization electrons in their target media, with large detector volumes and low background…
