Description
When thinking about Dark Matter, one always has the typical WIMP with a mass of a few
100 GeV in mind. In this talk, we will argue that another valid possibility is to
have sterile neutrinos at the keV scale ("Warm Dark Matter"), which can yield the
correct Dark Matter abundance when, e.g., produced non-thermally. The crucial
advantage of this framework is that we need some type of right-handed neutrino to
explain neutrino masses, which suggests an interesting connection of the Dark Matter
problem to particle physics model building. We will explain these connections and
present the most interesting models on the market.
