Summer Research 2024-Sophia Hollick

For many years the DAMA signal has been debated as to whether or not it can be attributed to dark matter. Both COSINE-100 (located in Y2L, Korea) and ANAIS-112 (located in LSC, Spain) have sought to end the debate by making a model-independent test using the same target material as DAMA, NaI(Tl). While both have published their own analyses, this research seeks to perform a combined search using data from both experiments.

Sophia Hollick is a Yale Physics Ph.D. student, and a member of Yale’s Wright Lab.  Hollick has been living as a visiting researcher in Zaragoza, Spain since September 2023 to perform the combined dark matter search between COSINE-100 and ANAIS-112.  She will continue to reside there until her expected graduation in May 2025. Preliminary results reaching a 3 sigma sensitivity to DAMA are expected to release next month at IDM 2024.
