Scalar induced resonant sterile neutrino production in the early Universe
F. Bezrukov, A. Chudaykin, D. Gorbunov
It has been recently suggested \cite{Bezrukov:2017ike,Bezrukov:2018wvd} that a cosmic scalar field can completely change the keV-scale sterile neutrino production in the early Univ…

Induced resonance makes light sterile neutrino Dark Matter cool
F. Bezrukov, A. Chudaykin, D. Gorbunov
We describe two new generation mechanisms for Dark Matter composed of sterile neutrinos with keV mass. The model contains a light scalar field which coherently oscill…
