XENON1T is the largest running liquid xenon detector for searching dark matter at Gran Sasso underground laboratory. The detector has been running in a stable condition for about one year and is delivering record-breaking exposure for dark matter direct detection. In this talk, I will present the details on the data reconstruction, selection, calibration and background analyses, leading...

The Particle and Astrophysical Xenon (PandaX) is a series of xenon-based ultra-low background experiments in the China Jinping underground Laboratory, aiming to search for Weakly-interacting massive particles (WIMPs) and to study neutrino properties. PandaX-II, with a 580-kg liquid xenon TPC currently under operation, is one of the leading WIMP direct detection experiment. In this talk, I...

The Large Underground Xenon (LUX) detector was a dual-phase xenon TPC with an active mass of 250 kg searching for Weakly Interacting Massive Particle (WIMP) dark matter via direct detection. It operated at the Sanford Underground Research Facility (SURF) in Lead, South Dakota from 2012-2016. This talk will report results from several new analyses: an effective field theory approach to explore...

We will report a search for annual and diurnal rate modulations using over 20 months of LUX data acquired between 2013 and 2016. This study focuses on electron recoil events at low energies. We obtained a low and stable event rate by using the innermost volume of the LUX detector and by developing robust cuts and corrections to address the observed time-dependence of the detector performance....

DarkSide uses a dual-phase Liquid Argon Time Projection Chambers to search for WIMP dark matter. The talk will present the latest result from the current experiment, DarkSide-50, running since mid 2015 a 50-kg-active-mass TPC, filled with argon from an underground source measured to contain lower Ar-39, the largest source of background, than atmospheric argon by a factor of >1000.

The DAMA/LIBRA set-up (about 250 kg highly radiopure NaI(Tl)) is currently in data taking at the Gran Sasso National Laboratory of the I.N.F.N. in its phase2. This experiment is dedicated to the investigation of Dark Matter (DM) particles in the galactic halo mainly by exploiting the model independent Dark Matter annual modulation signature. DAMA/LIBRA collected in its ?rst phase data over 7...

EDELWEISS is a phased direct Dark Matter search program looking for WIMPs in the GeV-TeV mass range with cryogenic Ge mono-crystals. The simultaneous measurement of heat via thermal sensors (NTDs) and ionization signals allows for discrimination of nuclear against electron recoils. We present our results of the first stage of EDELWEISS-III and discuss the currently ongoing R&D approaches and...

at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. The detector targets of CRESST-III are CaWO_4 crystals which are operated as cryogenic calorimeters at O(10)mK. The main event signature for a potential dark...
