keV Neutrino Dark Matter
In this talk, an introduction to keV sterile neutrinos as Dark Matter particles is given. After reviewing the cosmological aspects of (Warm) Dark Matter, I will explain why the topic is interesting for particle physics model building and also point out the differences to ordinary neutrino model building. We will go through a couple of generic models, all of which yield interesting and fundamental connections between the neutrino and the Dark Matter sectors. We finally present some alternative ideas and generalizations.
