Fig. 3: Expected DS-20k 90% C.L. exclusion limits for spin-independent WIMP–nucleon cross-section (σSI).
From: DarkSide-20k sensitivity to light dark matter particles

They are shown as bold red lines, assuming quenching fluctuations (QF) (dotted: fit from \({N}_{{e}^{-}}\) = 4, dashed: fit from \({N}_{{e}^{-}}\) = 2). One year of data is assumed. They are compared to the published 90% C.L. limits from DS-5014 and from other experiments7,25,26,27,28,29,30,31, with currently excluded parameter space shaded in light gray, as well as claimed discovery from Ref. 49. The neutrino fog in LAr with index n = 232 is also shown. A local dark matter density of 0.3 GeV c−2 cm−3 is assumed.
