Dark Matter, Baryogenesis and Neutrino Oscillations from Right Handed Neutrinos We study in detail under which circumstances three generations of right handed neutrinos with masses below the electroweak scale, coupled to the Standard Model via the usual type-I seesaw Lagrangian, can simultaneously explain neutrino oscillations, dark matter and the baryon asymmetry of the universe. In large parts of the allowed parameter space all three new particles can be detected directly or indirectly using present day experimental and observational techniques. Our results provide a guideline for experimental searches.
