Neutrino Dark Energy and Baryon Asymmetry from Higgs Sector
arXiv:0704.2020 · doi:10.1016/j.physletb.2007.07.014
Abstract
We propose a new model to explain the neutrino masses, the dark energy and the baryon asymmetry altogether. In this model, neutrinos naturally acquire small Majorana masses via type-II seesaw mechanism, while the pseudo-Nambu-Goldstone bosons associated with the neutrino mass-generation mechanism provide attractive candidates for dark energy. The baryon asymmetry of the universe is produced from the Higgs triplets decay with CP-violation.
