PandaX dark matter experiments use liquid xenon as target to search for dark matter particles at the China Jinping Underground Laboratory. The second phase of the experiments, PandaX-II, with 580 kg liquid xenon in the sensitive volume, has finished data taking in 2019 and collected 140 ton day of dark matter search data set in total. The next experiment under preparation, PandaX-4T, with 4...
The results of the first 6 independent annual cycles of DAMA/LIBRA–phase2 experiment deep underground at Gran Sasso are summarized; they correspond to a total exposure of 1.13 ton × yr. The DAMA/LIBRA–phase2, with lower energy threshold with respect to phase1, confirms the evidence of a signal that meets all the requirements of the model independent Dark Matter annual modulation signature, at...
The SuperCDMS SNOLAB experiment will probe a range of low-mass dark matter models with a suite of silicon and germanium detectors operated in both high-voltage and nuclear-recoil-discrimination modes. Plans for nuclear recoil yield measurements and our 4-tower initial payload strategy will be presented, as well as our expected physics reach for the first science run and beyond.
XENON1T is a tonne-scale liquid xenon time-projection chamber that operated from early 2016 through the end of 2018. With unprecedented low background levels and an energy threshold of about 1 keV (0.2 keV in ionization-only analyses), XENON1T is sensitive to a multitude of ultra-rare processes predicted by both Standard Model (SM) and Beyond-SM physics. In this talk I will discuss the most...
The ArDM experiment, a tonne-scale dual-phase liquid Argon TPC, has recently finished data taking in dual-phase mode. Earlier data taken in single-phase mode enabled us to reach a full understanding of all the instrumental and external background sources in the experiment. Recent data taken in dual-phase mode allows a further improvement of the experiment. In this talk the status of the...
The MAJORANA DEMONSTRATOR is an ultra-low background experiment operating on the 4850’
ulevel of the Sandford Underground Research Facility in South Dakota, which operates an
array of p-type point contact (PPC) high-purity germanium (HPGe) detectors made of both
natural materials as well as materials enriched in $^{76}$Ge. The surface exposure time of MAJORANA
enriched detectors was...
DEAP-3600 is a dark matter direct detection experiment located 2 km underground at SNOLAB (Sudbury, Canada). This single-phase detector consists of 3.3 tonnes of liquid argon (LAr), with an array of 255 photomultiplier tubes viewed through 50 cm of acrylic. The collaboration released dark matter search results from the first year of running (November 2016 to October 2017) last year, with a...
DAMIC-M is a next-generation experiment to search for dark matter with charge coupled devices (CCDs) in the Modane Underground Laboratory in France. It builds on the success of DAMIC at SNOLAB, which pioneered the detection of nuclear and electronic recoils in the bulk silicon of CCDs deployed in a low-background environment. The dominant source of noise in conventional CCDs lie in their...
COSINE-100 is a direct detection dark matter experiment that is testing DAMA/LIBRA’s claim of dark matter discovery. Located in South Korea’s Yangyang Underground Lab, COSINE-100 comprises 106 kg of sodium iodide detectors surrounded by a ~2000 L liquid scintillator veto. In this talk, I will discuss recent results from our experiment, including searches for a dark matter-induced annual...
ANAIS (annual modulation with NaI Scintillators) is a dark matter direct detection experiment
located at the Canfranc Underground Laboratory (LSC, Spain).
Its main goal is to test in a model independent way the DAMA/LIBRA
positive result: an annual modulation in the low-energy detection rate compatible
with the expected signal induced by WIMPs in the galactic halo.
ANAIS-112,...
PICO-40L is the most advanced bubble chamber using about 50kg of a fluorine rich target material. The detector has a new chamber concept without buffer fluid, eliminating the backgrounds associated with the water in contact with the active liquid in previous PICO bubble chambers. We will report the status of the commissioning and give a first indication of the background rates in the chamber.
