Dark Matter Candidates and Signals
University of California, Irvine
A quarter of the Universe is composed of dark matter, but what exactly dark matter is, no one knows. UC Irvine Professor of Physics and Astronomy Jonathan Feng will review recent progress in resolving this puzzle, focusing on several well-motivated possibilities, including WIMPs (weakly interacting massive particles) and related candidates. Feng will discuss the theoretical motivations for these candidates, their diverse implications at the interface of particle physics and cosmology, and the prospects for identifying dark matter in the coming years.
Feng's research interests combine theoretical particle physics, astroparticle physics and cosmology. He studies the universe at the smallest and largest length scales, with the goal of answering fundamental questions as to the existence of supersymmetric particles and extra spatial dimensions, and the nature of dark matter, dark energy and high-energy cosmic rays.
