摘要
In an extension of the Standard Model by three relatively light right-handed neutrinos (the vMSM model) the role of the dark matter particle is played by the lightest sterile neutrino. We demonstrate that the observations of the extragalactic x-ray background allow us to put a strong upper bound on the mass of the lightest active neutrino and predict the absolute values of the mass of the two heavier active neutrinos in the vMSM provided that the mass of the dark matter sterile neutrino is larger than 1.8 keV.
