Resonance production of keV sterile neutrinos in core-collapse supernovae and lepton number diffusion

Vsevolod Syvolap, Oleg Ruchayskiy, Alexey Boyarsky

We investigate how hypothetical particles - sterile neutrinos - can be produced in the interior of exploding supernovae via the resonant conversion of ${\bar{\nu }}_{\mu }$ and ${\bar{\nu }}_{\tau }$. The…
