Testing DAMA: discovery or background?

Astrophysical observations have provided convincing evidence for the existence of dark matter, yet direct observation of the dark matter particles has not been conclusively established. DAMA experiment claimed to have observed the annual modulation signal of dark matter using NaI detectors at the Gran Sasso Lab in Italy.  This result does match with search results with other type of detectors.   However, there is no satisfactory explanation for the apparent signal. 

Several experiments worldwide are working to perform a conclusively test of this claim.   In this talk, I will discuss results from the DM-Ice17 experiment, which has reported the first direct dark matter search result in the southern hemisphere. I will also present the status of the COSINE project, a collaborative effort between DM-Ice and KIMS.  It is poised to become the first experiment that can directly test DAMA’s result.
