Abstract
Time Projection Chambers filled with Ar in double phase are largely employed in the direct detection of Weakly Interacting Massive Particles (WIMPs) as Dark Matter candidates. Models predict WIMP with a mass at the electroweak scale, so the expected energy of the Ar nuclear recoil after a WIMP-induced scattering is in the range of tens of keV. However, if these particles had mass at the GeV/c2 scale, the deposited energy would drop to a few keV. In this scenario, WIMP direct detection will become challenging but still possible in these detectors, as proved by recent studies on the data collected by DarkSide-50. Since the future generation of multi-tonnes experiments aims to be sensitive also at this low-mass scale, the REcoil Directionality (ReD) experiment underwent a campaign to investigate the ionization response of LAr down to a few keV.
