Baryogenesis from a right-handed neutrino condensate

TL;DR

This paper proposes a unified model where a right-handed neutrino condensate drives both inflation and baryogenesis, making testable predictions with few parameters.

Contribution

It introduces a minimal, predictive framework linking neutrino condensates to inflation and baryon asymmetry, reducing the number of free parameters.

Findings

The model predicts the baryon asymmetry of the Universe.

It determines the mass of the right-handed neutrino.

It makes testable predictions for inflationary observables.

Abstract

We show that the baryon asymmetry of the Universe can be generated by a strongly coupled right handed neutrino condensate which also drives inflation. The resulting model has only a small number of parameters, which completely determine not only the baryon asymmetry of the Universe and the mass of the right handed neutrino but also the inflationary phase. This feature allows us to make predictions that will be tested by current and planned experiments. As compared to the usual approach our dynamical framework is both economical and predictive.
