Fig. 7: Discovery potentials for dark matter in different experimental settings.
From: The CRESST experiment towards the next generation of sub GeV direct dark matter detection
The four lower curves represent the 3σ discovery potential for spin-independent DM-nucleus scattering in the presence of solar neutrinos and no other backgrounds, assuming various exposures and thresholds. Below these curves, due to neutrinos presence a DM discovery becomes impossible. CRESST after the upgrade is expected to remain approximately two orders of magnitude above the neutrino fog, assuming detector thresholds of 30.1 eV. The upper curve (orange) is the sensitivity projection for the CRESST upgrade assuming a 100 times less LEE with 515 kg ⋅ day exposure (26 detectors of 2 g with 5 eV threshold (double dash double dotted) and 70 detectors of 23.6 g with 30.1 eV threshold (dashed) in 1 year of data taking). The gray region highlights the so-called neutrino fog, calculated for CaWO4 in ref. 48.
