Dark matter-electron scattering result from SNOLAB!

DAMIC's latest results on the search for light dark matter particles (MeV-scale masses) was posted today on the arXiv! Link.

These are the best exclusion limits on the existence of dark matter particles with masses in the 0.5–5.0 MeV range:

The 90 % C.L upper limits on the DM-electron free scattering cross section (σe) as a function of DM mass (mχ) for three different dark-matter form factors (FDM) obtained by DAMIC at SNOLAB (solid blue line).​ Other lines present results from competing experiments.
