Title: Non-Abelian Dark Matter and Dark Radiation
Host: Markus Luty
Room: 432
Abstract: I present a new model of WIMP dark matter in which dark matter is charged under a super-weakly coupled non-Abelian gauge group. The massless dark gluons of this dark gauge group contribute to the energy density of the universe as a form of dark radiation. I discuss experimental signatures of the dark matter (collider, direct, indirect) and dark radiation (CMB). In addition, the coupling between our dark matter and dark radiation has an impact on large scale structure formation. Interestingly, this coupling can remove the tension (2-3 sigma) between Planck's fit to the CMB and direct observations of large scale structure (sigma_8).
