Three-year annual modulation search with COSINE-100

COSINE-100 is a direct detection dark matter experiment that aims to test/LIBRA's claim of dark matter discovery by searching for a dark-induced annual modulation signal with NaI (Tl) detectors. We present new on the annual modulation signal from a dataset with a 2. 82 yr utilizing an active mass of 61. 3 kg, for a total exposure of 173\yr. This new result features an improved event selection that allows both lowering the energy threshold to 1 keV and a more precise-dependent background model. In the 1-6 keV and 2-6 keV energy intervals, observe best-fit values for the modulation amplitude of 0. 0067\0. 0042 0. 0051\0. 0047 counts/ (day\kg\keV), respectively, with a fixed at 152. 5 days.
