Dirac Neutrinos, Dark Energy and Baryon Asymmetry

TL;DR

This paper proposes a novel framework where Dirac neutrinos and a pseudo-Nambu-Goldstone boson explain dark energy and baryon asymmetry, linking neutrino mass generation to cosmological phenomena.

Contribution

It introduces a new origin for neutrino dark energy and baryon asymmetry using the Dirac seesaw mechanism and neutrinogenesis.

Findings

Neutrinos acquire small Dirac masses via the seesaw mechanism.

A pseudo-Nambu-Goldstone boson acts as a dark energy candidate.

Baryon asymmetry is explained through neutrinogenesis.

Abstract

We explore a new origin of neutrino dark energy and baryon asymmetry in the universe. The neutrinos acquire small masses through the Dirac seesaw mechanism. The pseudo-Nambu-Goldstone boson associated with neutrino mass-generation provides a candidate for dark energy. The puzzle of cosmological baryon asymmetry is resolved via neutrinogenesis.
