High Energy Seminar
Searching for the Identity of Dark Matter
Time: 3:00 pm
Place: 4274 Chamberlin
Speaker: Lauren Hsu, Fermilab
Abstract: Astrophysical observations have confirmed that ordinary matter<br> makes up only ~15% of the observable matter in the universe. The composition of the remaining non-luminous (dark) matter is<br> unknown. This is a time of great excitement. Efforts on<br> various fronts are racing to elucidate the particle nature of<br> dark matter. With a collection of germanium and silicon<br> crystals cooled to ~50 mK, the Cryogenic Dark Matter Search is<br> looking for the possible rare collision of a prime dark matter<br> candidate, the weakly interacting massive particle (WIMP), with<br> ordinary matter. I will report on recent results from CDMS<br> and discuss the status of the future experimental phases. These include the 10-kg phase of SuperCDMS, which is beginning<br> now, the 100-kg stage at SNOLAB, which has a projected start<br> date of 2013, and looking forward into the future, the 1-ton<br> GEODM.<br>
