TL;DR
This paper presents a left-right symmetric model of neutrino dark energy where the neutrino mass parameter remains naturally light, predicts a TeV-scale U(1)_R breaking, and can be integrated into grand unified theories, with implications for LHC signals and leptogenesis.
Contribution
It introduces a novel left-right symmetric framework for neutrino dark energy with a naturally light mass parameter and TeV-scale symmetry breaking, compatible with grand unification.
Findings
Neutrino masses predict a TeV-scale U(1)_R breaking.
Model remains natural with a light mass parameter.
Potential signals for LHC detection.
Abstract
We implemented the neutrino dark energy proposal in a left-right symmetric model. Unlike earlier models of mass varying neutrinos, in the present model the mass parameter that depends on the scalar field (acceleron) remains very light naturally. The required neutrino masses then predicts the U(1)_R breaking scale to be in the TeV range, providing new signals for LHC. Compared to all other neutrino dark energy proposals, this model has the added advantage that it can also be embedded into a grand unified theory. In this scenario leptogenesis occurs through decays of scalars at very high energy.
