COSINE experiment - A WIMP dark matter search experiment with NaI(Tl) detectors
Hyunsu Lee, IBS, Korea
The COSINE experiment searches for interactions of Weakly Interacting Massive Particles (WIMPs) using an array of NaI(Tl) crystal detectors in the 700-m-deep Yangyang underground laboratory, Korea. The main goal is to check the annual modulation signal observed by DAMA/LIBRA with the same target material. The first phase of the experiment, COSINE-100 with 106 kg of NaI(Tl) crystals, has been running stably for more than 4 years. Several analyses in addition to the annual modulation have been actively ongoing, based on the 1 keV energy threshold and about 3 counts/day/kg/keV background rate in an energy region between 1 and 6 keV. In this talk, the detector performance, recent analysis results, and future prospects of the COSINE experiment will be presented.
