Physics Department Colloquium
Knowing So Little about So Much
Time: 3:30 pm - 5:00 pm
Place: Chamberlin 2241
Speaker: Hooman Davoudiasl , Brookhaven National Laboratory
Abstract: The dominant forms of matter and energy in the Universe are of unknown origin. In particular, the presence of dark matter (DM) - constituting roughly a quarter of the cosmic energy budget - has been established only through its gravitational effects and its nature remains largely a mystery. In this talk, we will briefly discuss some general aspects of DM theory and observation. It is possible that DM belongs to a separate sector, including various states and new forces. We will discuss some of the ways that such a sector may communicate with our visible world and reveal itself in current and future experiments.
Host: Lisa Everett and Aki Hashimoto
