Recoiling Against the Dark Universe: CDMS and the Hunt for Dark Matter

Abstract:

The first evidence for dark matter dates back to observations of the Coma cluster made by Fritz Zwicky in 1933. Since that time, astrophysicists and astronomers have produced compelling evidence for the existence of dark matter and determined that it constitutes the bulk of the matter in the Universe. Despite this fact, the composition of the dark matter remains unknown. One compelling candidate for particle dark matter is the Weakly Interacting Massive Particle (WIMP). Working in a low-background environment in the Soudan Mine in northern Minnesota, the CDMS experiment is designed to directly detect interactions between WIMPs and nuclei in its target Ge and Si crystals.

In this talk I will present recent results from and the current status of the CDMS experiment. I will also discuss plans for a future 25-kg experiment which is planned for operation in SNOLab.

Dr. Cooley-Sekula is a short-listed candidate for the advertised position in Experimental Particle Astrophysics. She will be in the Department on December 6th and 7th.
