Inflationary Cosmology and Superluminal Neutrinos

TL;DR

This paper proposes a model where Lorentz-violating backgrounds lead to superluminal neutrinos at high energies and connect to dark energy at low energies, offering a unified explanation for both phenomena.

Contribution

It introduces a novel scenario linking superluminal neutrinos and dark energy through a distance-dependent Lorentz violation.

Findings

Superluminal neutrinos can arise at high energies due to Lorentz violation.

A similar mechanism approaches subluminal behavior at low energies.

The model potentially unifies explanations for superluminal neutrinos and dark energy.

Abstract

We show that in the presence of a distance dependent Lorentz-violating time-like background one may find superluminal neutrinos at some high energy such as OPERA's scale. The similar behavior but approaching the subluminal branch is found to appear for inflaton field in the low energy scale. Thus this scenario seems to be suitable to acomplish both superluminal neutrinos and dark energy.
