A new life for sterile neutrino dark matter after the pandemic

Torsten Bringmann, Paul Frederik Depta, Marco Hufnagel +3

We propose a novel mechanism to generate sterile neutrinos ${\nu }_s$ in the early Universe, by converting ordinary neutrinos ${\nu }_{\alpha }$ in scattering processes ${\nu }_s{\nu }_{\alpha }\to {\nu }_s{\nu }_s$. After init…
