The SuperCDMS SNOLAB experiment is a direct dark matter (DM) search experiment under construction at the SNOLAB underground laboratory in Sudbury , Canada. It will focus on the search for low mass DM candidates by employing cryogenic Ge and Si detectors, with expected world-leading sensitivity for particles with masses in the range between 0.5 and 5 GeV/c$^2$. Two types of detectors are...

To circumvent the problem of the large background of events with no ionisation signal ("Heat-Only" events) that limit the sensitivity of our detectors equipped with Ge-NTD sensors, the collaboration has tested the use of NbSi Transition Edge... -

The DAMIC-M experiment will search for dark matter particles via direct detection using thick, fully depleted silicon charge-coupled devices (CCDs) with a target exposure of 1 kg-year. The CCDs have been enhanced with the skipper readout technology which allows for single electron resolution through multiple non-destructive measurements of the individual pixel charge, lowering the detection...

SENSEI (Sub-Electron Noise Skipper Experimental Instrument) is a direct detection dark matter experiment with detectors operating at Fermilab and at the SNOLAB underground facility. The experiment consists of silicon Skipper-CCD sensors that make multiple non-destructive measurements of the charge contained in each of millions of pixels, reducing the readout noise to a level that allows for...

The electron-counting capability of the skipper-CCD technology is allowing it to lead the search for DM-electron interactions in the low-mass regime with g-size experiments. There are ongoing efforts for developing massive direct DM search experiments with this technology. Oscura, an array of ~20,000 silicon skipper-CCDs (10 kg), is the biggest within them. Its final goal is to have less than...

The CRESST experiment (Cryogenic Rare Event Search with Superconducting Thermometers) is searching for nuclear recoils induced by dark matter particles in cryogenic detectors employing different target materials: CaWO$_4$, Al$_2$O$_3$, LiAlO$_2$, and Si. With detection thresholds for nuclear recoils as low as 10 eV, CRESST is extremely suitable in the search for low mass dark matter particles....

The XENON collaboration has developed a series of liquid xenon detectors to lead the search for WIMP dark matter. The tonne-scale liquid xenon detectors (such as XENON1T and XENONnT) are sensitive not only to WIMP dark matter but also to the Solar Boron-8 neutrinos. In this talk, I will describe how to improve the analysis of XENON1T and XENONnT data to enhance their sensitivities to Boron-8...

In recent years, direct dark matter detection experiments extended the hunt for dark matter to masses well below 1GeV, driven by lowering their thresholds to the scale of few eV. However, with the lower thresholds, the experiments started to observe events above the expected background level. Numerous low-threshold experiments observe suchlike EXCESSES of events, a common feature of the...
