Dark Matter: The Case of Sterile Neutrino
Abstract
An extension of the Standard Model by three right-handed neutrinos with masses smaller than the electroweak scale (the MSM) can explain simultaneously dark matter and baryon asymmetry of the Universe, being consistent with the data on neutrino oscillations. A dark matter candidate in this theory is the sterile neutrino with the mass in keV range. We discuss the constraints on the properties of this particle and mechanisms of their cosmological production. Baryon asymmetry generation in this model is reviewed. Crucial experiments that can confirm or rule out the MSM are briefly discussed.
