Sterile Neutrinos in $E_{\rm 6}$

TL;DR

This paper explores how the exceptional group $E_6$ can naturally incorporate three sterile neutrinos, discussing the theoretical implications of this framework.

Contribution

It presents a novel theoretical model embedding three sterile neutrinos within the $E_6$ grand unified theory.

Findings

The $E_6$ group can accommodate three sterile neutrinos.

Implications for neutrino physics are discussed.

Potential experimental signatures are considered.

Abstract

The opportunity to accommodate three flavors of sterile neutrinos exists within the exceptional group $E_{\rm 6}$. Implications of this description are discussed.
