Plasma Effects Suppress Mixing-Induced Collisional Freeze-In
Using first-principles nonequilibrium Kadanoff-Baym equations, this paper demonstrates that plasma effects suppress collisional freeze-in by replacing the vacuum mixing angle with a plasma-corrected counterpart, thereby ruling out keV-MeV sterile neutrinos as dark matter produced from the Standard Model plasma.
