TLDR
COSINE-100 as mentioned in this paper is a dark matter search experiment based on an array of low background NaI(Tl) crystals located at the Yangyang underground laboratory in China.Abstract:
COSINE is a dark matter search experiment based on an array of low background NaI(Tl) crystals located at the Yangyang underground laboratory. The assembly of COSINE-100 was completed in the summer of 2016 and the detector is currently collecting physics quality data aimed at reproducing the DAMA/LIBRA experiment that reported an annual modulation signal. Stable operation has been achieved and will continue for at least 2 years. Here, we describe the design of COSINE-100, including the shielding arrangement, the configuration of the NaI(Tl) crystal detection elements, the veto systems, and the associated operational systems, and we show the current performance of the experiment.read more

TL;DR: In this paper, the COSINE-100 experiment was used to determine whether there is evidence for an excess of events above the expected background in sodium iodide and to look for evidence of an annual modulation.

TL;DR: The annual modulation analysis of 1.5 years of data from ANAIS-112 supports the estimated sensitivity for the accumulated exposure, which supports the projected goal of reaching a 3σ sensitivity to the DAMA/LIBRA result in five years of data taking.

TL;DR: The SNO+ experiment as mentioned in this paper is located 2 km underground at SNOLAB in Sudbury, Canada and performs a low background search for neutrinoless double beta (0) decay using 780 tonnes of liquid scintillator loaded with 3.9 tonnes of natural tellurium, corresponding to 1.3 tonnes of [130]Te.

TL;DR: In this paper, the authors study the compatibility of the observed modulation signal with DM scattering and find that canonical spin-independent DM-nucleon interactions are no longer a good fit to the observed signal in the standard halo model.
