Quantum breaks in a model for the evolution of neutrinos during their decoupling era in the big bang

21 Aug 2020  ·  Sawyer R. F. ·

An active two-neutrino state's coupling to an intermediate scalar meson, and thence to a two-antineutrino state, is one idea for catalyzing transitions from active to sterile neutrinos, in an implementation of the Dodelson-Widrow proposal for the production of sterile and somewhat massive neutrinos as dark matter candidates. We propose some mechanics that promises to use the very same model with the same mass and coupling parameters, in order to achieve similar results, but orders of magnitude faster; or alternatively, similar results but beginning with vastly reduced coupling constants... The model then would become much less constrained by consistency with laboratory and astrophysical data. read more
