The CRESST experiment is a direct dark matter search which aims to measure interactions of potential dark matter particles in an earth-bound detector. With the current stage, CRESST-III, we focus on a low energy threshold for increased sensitivity towards light dark matter particles. In this manuscript we describe the analysis of one detector operated in the first run of CRESST-III (05/2016-02/2018) achieving a nuclear recoil threshold of 30.1 eV. This result was obtained with a 23.6 g CaWO 4 crystal operated as a cryogenic scintillating calorimeter in the CRESST setup at the Laboratori Nazionali del Gran Sasso (LNGS). Both the primary phonon/heat signal and the simultaneously emitted scintillation light, which is absorbed in a separate silicon-on-sapphire light absorber, are measured with highly sensitive transition edge sensors operated at ∼ 15 mK. The unique combination of these sensors with the light element oxygen present in our target yields sensitivity to dark matter particle masses as low as 160 MeV/c 2 .

“…Sensitivities to 100 MeV/c 2 -scale SIMPs with spinindependent cross section of the order of 10 −30 cm 2 have been reported in [60]. These were derived based on the dark counts observed in a photo-multiplier tube coupled to a liquid scintillator cell operated in a shallow site with 6 meter water equivalent overburden.…”

they elastically scatter off nuclei [4,5]. In recent decades, significant advances have been made in the search for WIMPs in the GeV/c 2 -to TeV/c 2 -range that is natural for Supersymmetry [6][7][8]. However, in the light of the absence of signal in that region there is an increasing interest in DM particles in the GeV/c 2 and sub-GeV/c 2 mass range [9][10][11][12][13][14][15]. These searches require experimental thresholds as low as a few tens of eV, a performance that can be attained by cryogenic detectors [16,17]. A particular advantage of such detector technology is that the thermal signal is not affected by the strong quenching effects that tend to severely reduce the amplitude of ionization or scintillation signals at low energy. This paper describes the results obtained by the EDELWEISS collaboration with a 33.4-g Ge detector demonstrating that such a device equipped with a neutron-transmutation-doped Ge (Ge-NTD) sensor [18] can reach the sensitivity to probe the sub-GeV domain. As a proof of the relevance of this technology, it is used in

Cryogenic Rare Event Search with Superconducting Thermometers (CRESST) is a long-standing direct dark matter detection experiment with cryogenic detectors located at the underground facility Laboratori Nazionali del Gran Sasso in Italy. CRESST-III, the third generation of CRESST, was specifically designed to have a world-leading sensitivity for low-mass dark matter (DM) (less than 2 GeV/c 2) to probe the spin-independent DM-nucleus cross section. At present, a large part of the parameter space for spin-independent scattering off nuclei remains untested for dark matter particles with masses below few GeV/c 2 although many motivated theoretical models having been proposed. The CRESST-III experiment employs scintillating CaWO 4 crystals of ∼ 25 g as target material for dark matter interactions operated as cryogenic scintillating calorimeters at ∼ 10 mK. CRESST-III first data taking was successfully completed in 2018, achieving an unprecedented energy threshold for nuclear recoils. This result extended the present sensitivity to DM particles as light as ∼ 160 MeV/c 2. In this paper, an overview of the CRESST-III detectors and results will be presented.
