An extension of the minimal standard model by three right-handed neutrinos with masses smaller than the electroweak scale (the νMSM) allows to explain simultaneously neutrino oscillations and dark matter in the universe. We show how to fix the absolute values of the active neutrino masses in this model. © 2006 IOP Publishing Ltd.
