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

TL;DR

This paper explores a neutrino evolution model during the early universe's decoupling era, proposing mechanics that could produce sterile neutrinos more efficiently or with weaker interactions, potentially easing experimental constraints.

Contribution

It introduces a novel mechanism within an existing neutrino model to accelerate sterile neutrino production or reduce coupling strength, enhancing compatibility with observational data.

Findings

Proposes a faster neutrino transition mechanism.

Suggests reduced coupling constants are sufficient.

Potentially relaxes experimental constraints.

Abstract

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.
