Limits on WIMP Dark Matter with NaI(Tl) Crystals in Three Years of COSINE-100 Data

Author(s): G. H. Yu et al. (COSINE-100 Collaboration) We report limits on weakly interacting massive particle (WIMP) dark matter derived from three years of data collected by the COSINE-100 experiment with NaI(Tl) crystals, achieving an improved energy threshold of 0.7 keV. This lowered threshold enhances sensitivity in the sub-GeV mass range, extendin… [Phys. Rev. Lett. 135, 231001] Published Tue Dec 02, 2025
