The first search for a dark matter annual modulation signal with NaI(Tl) target material in the Southern Hemisphere conducted with the DM-Ice17 experiment is presented. DM-Ice17 consists of 17 kg of NaI(Tl) scintillating crystal under 2200 m.w.e. overburden of Antarctic glacial ice. The analysis presented here utilizes a 60.8 kg yr exposure. While unable to exclude the signal reported by DAMA/LIBRA, the DM-Ice17 data are consistent with no modulation in the energy range of 4-20 keV, providing…

Results from the DM-Ice17 Dark Matter Experiment at the South Pole

DM-Ice is a phased experimental program using low-background NaI(Tl) crystals with the aim to unambiguously test the claim of dark matter detection by the DAMA experiments. DM-Ice17, consisting of 17

Search for a Dark Matter-Induced Annual Modulation Signal in NaI(Tl) with the COSINE-100 Experiment.

New constraints on the dark matter-induced annual modulation signal are presented using 1.7 years of COSINE-100 data with a total exposure of 97 kg yr and best fit values for modulation amplitude and phase are observed.

Direct dark matter search by annual modulation with 2.7 years of XMASS-I data

An annual modulation signal due to the Earth orbiting around the Sun would be one of the strongest indications of the direct detection of dark matter. In 2016, we reported a search for dark matter by

ANAIS-112 sensitivity in the search for dark matter annual modulation

The annual modulation measured by the  DAMA/LIBRA experiment can be explained by the interaction of dark matter WIMPs in NaI(Tl) scintillator detectors. Other experiments, with different targets or

Analysis of backgrounds for the ANAIS-112 dark matter experiment

The ANAIS (Annual modulation with NaI(Tl) Scintillators) experiment aims at the confirmation or refutation of the DAMA/LIBRA positive annual modulation signal in the low energy detection rate, using

Results from the first cryogenic NaI detector for the COSINUS project

Recently there is a flourishing and notable interest in the crystalline scintillator material sodium iodide (NaI) as target for direct dark matter searches. This is mainly driven by the long-reigning

Sub-GeV Dark Matter Searches and Electric Field Studies for the LUX and LZ Experiments

The nature of dark matter (DM) remains a mystery since it has so far eluded detection in the laboratory. To that end, the Large Underground Xenon (LUX) experiment was built to directly observe the

Background model for the NaI(Tl) crystals in COSINE-100

To understand measured backgrounds in the NaI(Tl) crystals, Monte Carlo simulations using the Geant4 toolkit are performed and background models for each crystal are developed that consider contributions from both internal and external sources, including cosmogenic nuclides.

Direct search for dark matter with the DarkSide experiment

A wide range of observational evidence suggests that the matter content of the Universe is dominated by a non-baryonic and non-luminous component: dark matter. One of the most favoured candidate for
