First result of annual modulation search has been published in Phys. Rev. Lett.

We present new constraints on the dark matter-induced annual modulation signal using 1.7 years of COSINE-100 data with a total exposure of 97.7 kg yr. The COSINE-100 experiment, consisting of 106 kg of NaI(Tl) target material, is designed to carry out a model-independent test … Continue reading

First direct search of iBDM with COSINE-100 was published in Phys. Rev. Lett as an Editors’ suggestion (April/3th, 2019).

A search for inelastic boosted dark matter (IBDM) using the COSINE-100 detector with 59.5 days of data is presented. This relativistic dark matter is theorized to interact with the target material through inelastic scattering with electrons, creating a heavier state … Continue reading

First annual modulation search from COSINE-100

COSINE-100 report the results from the search for a dark matter-induced annual modulation signal in NaI(Tl) based on 1.7 years of COSINE-100 data. The result is consistent with both a null hypothesis and DAMA/LIBRA’s 2-6 keV best fit value. arXiv:1903.10098

COSINE-100 initial 59.9 days data indicate no dark-matter induced events, significantly challenging the DAMA claim
