Experimental signatures of cosmological neutrino condensation

TL;DR

This paper proposes that cosmological neutrino superfluid condensation could explain neutrino oscillations and dark energy, and suggests laboratory beta decay experiments could detect signatures of this phenomenon.

Contribution

It introduces the idea that neutrino condensation at cosmological scales can solve key cosmological problems and proposes experimental tests to verify this hypothesis.

Findings

Neutrino condensation can produce a small cosmological constant.

It can generate tiny Majorana neutrino masses.

Laboratory beta decay experiments can detect signatures of neutrino condensation.

Abstract

Superfluid condensation of neutrinos of cosmological origin at a low enough temperature can provide simple and elegant solution to the problems of neutrino oscillations and the accelerated expansion of the universe. It would give rise to a late time cosmological constant of small magnitude and also generate tiny Majorana masses for the neutrinos as observed from their flavor oscillations. We show that carefully prepared beta decay experiments in the laboratory would carry signatures of such a condensation, and thus, it would be possible to either establish or rule out neutrino condensation of cosmological scale in laboratory experiments.
