The Light Side of Dark Matter

One of the most pressing issues currently facing particle physics (as well as astrophysics and cosmology) is the identity of dark matter. If dark matter is a particle, particle physicists hope to produce and study it in high energy collisions at the Large Hadron Collider (LHC) located at CERN. The search for particle dark matter, however, is not constrained to only the LHC. In fact, direct detection searches (which look for "local" dark matter particles interacting with normal matter) have made huge strides over the past several years and are quickly closing in on electroweak-scale couplings and masses. In this talk, I will discuss an alternative search method which looks for signals of dark matter from its annihilation (or decay) products. In particular, I will focus on the possibility of detecting dark matter through its annihilation into photons. These annihilations produce spectacular signals that could provide a smoking gun for particle dark matter and, in the case where there are more than one particle in the "dark sector", could help lead to the discovery of new physics at the LHC.
