Inflation might be caused by the right
Gabriela Barenboim (U. Valencia, IFIC)

TL;DR
This paper proposes that the inflaton field responsible for cosmic inflation could originate from a strongly coupled right-handed neutrino condensate, linking neutrino physics with early universe cosmology and making testable predictions.
Contribution
It introduces a novel inflation model where the inflaton arises from a right-handed neutrino condensate, connecting neutrino mass generation with inflationary dynamics.
Findings
The model constrains the right-handed neutrino mass and inflaton properties.
Predictions are testable with current and future experiments.
The model aligns neutrino physics with inflationary cosmology.
Abstract
We show that the scalar field that drives inflation can have a dynamical origin, being a strongly coupled right handed neutrino condensate. The resulting model is phenomenologically tightly constrained, and can be experimentally (dis)probed in the near future. The mass of the right handed neutrino obtained this way (a crucial ingredient to obtain the right light neutrino spectrum within the see-saw mechanism in a complete three generation framework) is related to that of the inflaton and both completely determine the inflation features that can be tested by current and planned experiments.
