Cosmon as the Modulon: Non-Gaussianity from Dark Energy
Chian-Shu Chen, Chia-Min Lin
TL;DR
This paper explores how a model involving dark energy and neutrino growth can lead to non-Gaussian features in the early universe, using a Higgs triplet as the inflaton in a chaotic inflation scenario.
Contribution
It introduces a novel mechanism linking dark energy, neutrino growth, and non-Gaussianity through a Higgs triplet-driven inflation model.
Findings
Potentially detectable non-Gaussianity signatures.
Connection between dark energy dynamics and inflation.
New inflationary scenario involving Higgs triplet.
Abstract
In this paper, we show that the idea of growing neutrino can result in a modulated reheating effect and produce detectable non-Gaussianity in the model where the Higgs triplet from type II seesaw mechanism plays the role of the inflaton in chaotic inflation.
