EDELWEISS is a direct Dark Matter search program looking for WIMPs in the GeV-TeV mass range. For that purpose, an array of cryogenic Ge mono-crystals read out simultaneously by NTD thermal sensors and by surface electrodes is installed in the Modane underground laboratory. We present a summary of EDELWEISS-II results including limits on axion couplings. For EDELWEISS-III a major upgrade of...

First postulated more than 80 years ago to address the 'missing mass' of the Milky Way galaxy Dark Matter remains as one of the best motivations for Physics Beyond the Standard Model. The Large Underground Xenon (LUX) experiment is a 350kg liquid xenon time projection chamber designed to directly detect galactic dark matter. Currently deployed 1 mile underground in the Sanford Underground...

The existence of a photon-like massive particle, the gamma' or dark photon, is postulated in several extensions of the Standard Model. Such a particle could indeed
help to understand the puzzling behavior of the observed cosmic positron fraction
as well as to solve the sofar unexplained deviation between the measured and
calculated values of the muon g−2 anomaly. The dark photon, unlike its...

DarkSide-50 (DS-50) at Gran Sasso underground laboratory, Italy, is a
direct dark matter search experiment based on a TPC with liquid argon
from underground sources. The DS-50 TPC, with 50 kg of active argon
and a projected fiducial mass of >33 kg, is installed inside an active
neutron veto based on a boron-loaded organic scintillator. The neutron
veto is built inside a water...

CRESST is a cryogenic direct Dark Matter search experiment based on phonon-light technique. It is aiming for the detection of weakly interacting massive particles (WIMPs) via their elastic scattering off nuclei in CaWO4 target crystals.
Significant improvements have been achieved with respect to previous measuring campaigns in terms of the intrinsic radiopurity of CaWO4 crystals and the...

The XENON100 detector, which is being operated at the Gran Sasso Underground Laboratory, is a dual phase (liquid-gas) xenon time-projection chamber for particle detection. The total amount of liquid xenon is 161 kg, of which 62 kg are in the active target enclosed in a Teflon/copper structure, the rest being in the surrounding active veto. The direct and proportional UV light signal produced...

Gravitational accretion of dark matter in neutron stars may constitute a mechanism to check for further indirect effects of its existence. In this way, dark matter annihilations taking place within such compact astrophysical objects may prevent the appearance of additional particle population of hadrons inside the neutron star core. We discuss on the experimental consequences of this possibility.

The recently formed PICO collaboration, a merger of COUPP and PICASSO, is designing a 250L bubble chamber to search for dark matter in the form of Weakly Interacting Massive Particles (WIMPs). This experiment will have nearly four orders of magnitude greater sensitivity to spin-dependent WIMP-nucleon interactions as compared to our existing world-best results. We operate bubble chambers with...
