"Hints and Traces: Chasing the Dark Matter Wind''

The universe contains at least five times more dark matter than normal matter, such as atoms. The existence of dark matter is demonstrated by its gravitational interactions, but the properties of these mysterious "dark'' particles are unknown. The motion of our solar system around the galactic center should produce an apparent dark matter wind, which may enable the definitive observation of dark matter particles. The nature of dark matter is one of the key questions today in physics and astrophysics. A world-wide race is on to directly observe dark matter particles interacting in terrestrial detectors. This search requires the most sensitive detectors and cleanest environments in the history of particle physics. I will describe the evidence for dark matter, and the hunt for the dark matter wind.

Refreshments will be served in CP 179 at 3:15 PM
