Strong constraints from COSINE-100 on the DAMA dark matter results using
  the same sodium iodide target
  We present new constraints on dark matter interactions using 1.7 years of
COSINE-100 data. The COSINE-100 experiment, consisting of 106 kg of
tallium-doped sodium iodide (NaI(Tl)) target material, is aimed at testing
DAMA's claim of dark matter observation using the same NaI(Tl) detectors.
Improved event selection requirements, a more precise understanding of the
detector background and the use of a larger data set considerably enhances the
COSINE-100 sensitivity for dark matter detection. No signal consistent with the
dark matter interaction is identified, and rules out model-dependent dark
matter interpretations of the DAMA signals in the specific context of standard
halo model with the same NaI(Tl) target for various interaction hypotheses.
