Thesis Title: A Model-Independent Search for Dark Matter-Induced Annual Modulation Signal with the COSINE-100 Experiment

Experiments

DM-Ice

Maruyama, Heeger

Science Goal: DM-Ice is a direct-detection dark matter experiment to test DAMA’s assertion that the observed annual modulation is due to dark matter.  DM-Ice aims to understand the origin of DAMA’s signal by using the same target, and is the only experiment with access to both Northern and Southern Hemispheres.  DM-Ice is a phased experimental program; the current phase is COSINE-100.

WL Involvement: Reina Maruyama was the Principal Investigator of the experiment.

Science goal: Search for direct detection of dark matter, probing for an annual modulation in the signal reported by the DAMA/ LIBRA collaboration.

WL involvement: Maruyama is the PI and scientific co-spokesperson of COSINE-100.
