| contents | The COSINE project aims to independently test the DAMA experiment's long-standing claim of detecting dark matter interactions using the same NaI(Tl) scintillating crystal technology. In its first phase, COSINE-100 collected over six years of data at the Yangyang Underground Laboratory and achieved a three-sigma exclusion of the DAMA modulation signal under standard dark matter assumptions. The experiment is now being upgraded to the COSINE-100 Upgrade, deploying higher-light-yield NaI(Tl) detectors at the new, deeper Yemilab facility to further enhance sensitivity. Here, I will discuss the model-dependent WIMP searches performed with COSINE-100 and provide an update on the ongoing upgrade effort, highlighting its future prospects for crystal-based dark matter direct detection in Korea. |
