Complete $E_8$ Unification in 10 Dimensions

TL;DR

This paper presents a 10-dimensional grand unification model based on a single E8 gauge superfield, which, through orbifold compactification and Wilson lines, breaks down to the Standard Model while remaining anomaly-free.

Contribution

It demonstrates a complete unification of the Standard Model within a single E8 gauge superfield in 10 dimensions, using orbifold compactification without extra fields.

Findings

Model is anomaly free at all levels

Symmetry breaking achieved via orbifold and Wilson lines

Standard Model gauge group obtained from E8 in 10D

Abstract

A grand unification model with a single $E_8$ gauge superfield in 10 dimensions is presented. It is shown that, through the orbifold $T^6/(\mathbb{Z}_6\times \mathbb{Z}_2)$ and its corresponding Wilson lines, the symmetry is broken to the Standard Model one. Furthermore it is shown that the model is anomaly free at all levels without the need to add any extra field content. Thus a complete unification of the Standard Model into a single gauge superfield is achieved consistently.
