Abstract
The COSINE-100 is a direct WIMP search experiment that uses 106 kg of NaI(Tl) crystals as its target material. The experiment has started its data taking in September 2016, and has finished in March 2023, with exposure time ∼6 years. Primary goal of the experiment is to test the dark matter signal observed by the DAMA/LIBRA experiment. The DAMA/LIBRA has claimed to observe annual modulation signal behavior of data, which is compatible with profile of WIMP signal. However, no other experiment has succeeded to find WIMP signal yet. COSINE-100 aims to directly test the DAMA/LIBRA, by using same target material. Here we present the summary of recent WIMP search result in COSINE-100, in terms of spectral analysis and time dependent modulation search analysis. In addition to this, upgrades on COSINE-100 detector for next phase experiment is also summarized.
