Sculpting the Standard Model from low-scale Gauge-Higgs-Matter $E_8$ Grand Unification in ten dimensions

Abstract

A model with complete supersymmetric unification of the Standard Model matter content, interactions and families replication into a single E 8 gauge superfield in ten dimensions is presented. The gauge and extended Poincaré symmetries are broken through compactification of the T 6 /(Z 3 × Z 3 ) orbifold with Wilson lines, which reduces the original symmetry and matter content into those of the Standard Model. Proton decay is strongly suppressed automatically, while the unification scale is required to be as low as 10 6 − 10 9 GeV so that the corresponding physics may be potentially accessible and testable by future collider measurements. Such a low-scale Grand Unification concept yields a highly-constrained and predictive New Physics framework in a minimal and phenomenologically testable and consistent way.

“…Therefore, the study of simplified frameworks that can later be mapped to the low-energy limit of a certain UV complete framework can help in constraining their viable parameter space. In particular, some of the authors have proposed a GUT framework, which unifies all matter, Higgs and gauge sectors within the E 8 group, either at a conventional high-scale scenario [5,6], or a low-scale one [7,8]. It turns out that, as a common prediction of any of such proposals, the presence of new doublet Vector-Like Lepton (VLL) particles at the TeV scale or below is expected.…”
