- Barnard Hall Room 103
Peter Sorenson, Senior Scientist at Lawrence Berkeley National Laboratory, will present "Status and Outlook for the Direct Detection of Galactic Dark Matter". We know dark matter exists in the universe due to its gravitational interaction. But in order to study its microscopic properties we need the ability to observe it in the laboratory, via a different interaction. I will briefly review the leading technologies and the null result status of searches for interactions of dark matter with ordinary matter. It is often asked "if we continue to turn up null results, when should we stop searching for matter – dark matter interactions?". In the case of the long-favored Weakly Interacting Massive Particle (WIMP) model, predicted by Supersymmetry, the answer is easy: searches as we know them will end when an experiment reaches a sensitivity corresponding to the neutrino detection limit. New technologies will be required to push beyond this barrier. I will describe the instrumentation challenges for reaching this limit, and discuss ideas to build new or upgrade current experiments to reach this milestone.
