DEAP-3600 is a dark matter direct detection experiment operating 2 km underground at SNOLAB (Sudbury, Canada). This single-phase detector consists of 3.3 tonnes of liquid argon (LAr), viewed by an array of 255 photomultiplier tubes through 50 cm of acrylic. The collaboration has recently released dark matter search results from the first year of running (November 2016 to October 2017), with a...

DEAP-3600 is searching for dark matter particle interactions on several tonnes of liquid argon at SNOLAB. The detector, operating since late 2016, contains 3.3 tonnes of argon in a large ultralow-background spherical acrylic vessel and detects interactions by observing scintillation photons. Excellent pulse-shape discrimination between nuclear and electronic recoils has been demonstrated in...

A search for inelastic scattering of Weakly Interacting Massive Particles (WIMPs) off $^{129}$Xe was conducted in XMASS-I.
In the inelastic scattering, the nucleus of $^{129}$Xe is excited via spin-dependent interaction.
For a more sensitive search, a particle identification using the waveform was introduced to
separate the beta-ray events and the others.
Using XMASS-I data ($\mathrm{800\;...

The DarkSide-50 direct-detection dark matter experiment is a dual-phase argon time projection chamber operating at Laboratori Nazionali del Gran Sasso (LNGS) of INFN. It is sensitive to WIMPs with masses above 50 GeV/c2 by exploiting the exceptional pulse shape discrimination of the scintillation signal in LAr. A blind analysis, using (16,660+-270) kg d exposure using a target of...

The China Dark Matter Experiment (CDEX), located at the China Jinping Underground Laboratory (CJPL) whose overburden is about 2400m rock, aims at direct searches of light Weakly Interacting Massive Particles (WIMPs). A single-element 994-gram p-type point contact (PPC) germanium detector (CDEX1B) runs inside a solid passive shielding system. To achieve lower background, a prototype 10kg PPC...

The LUX (Large Underground Xenon) was a dark matter experiment using a two-phase Xe Time Projection Chamber located at the Sanford Underground Research Facility (SURF) in Lead, South Dakota 2012-2017. It previously published three separate world-leading limits on the spin-independent cross-section for Weakly Interacting Massive Particle (WIMP) dark matter via direct detection, with a fiducial...
