The results are based on a method that exploits the extremely low levels of leakage current of the DAMIC detector at SNOLAB of 2–6×10^-22 A cm^−2. We evaluate the charge distribution of pixels that collect <10e- for contributions beyond the leakage current that may be attributed to dark matter interactions. Constraints are placed on so-far unexplored parameter space for dark matter masses between 0.6 and 100 MeV c^-2. We also present new constraints on hidden-photon dark matter with masses in the range 1.2–30 eV c^-2.

The European Research Council ''selects and funds the very best, creative researchers of any nationality to run projects based in Europe'', with Principal Investigators of Advanced Grants identified as ''exceptional leaders in terms of originality and significance of their research contributions.'' Learn more >> The WIMP cross-section σ χ−n The WIMP cross-section σ χ−n Upper limit (90% C.L.) on the WIMP cross-section σ χ−n obtained with a small data set taken during DAMIC100 R&D phase (red line). Even if limited by the exposure and the level of radiogenic background — both to significantly improve in the upcoming DAMIC100 — these results demonstrate DAMIC’s sensitivity in the low-mass WIMP region (<10 GeV c−2), where the experiment is particularly competitive thanks to its low energy threshold.
