Abstract

A model is presented that achieves unification of the full Standard Model (SM) field content into a single superfield. It has E₈ as a gauge group and simple SUSY in ten spacetime dimensions. The extra dimensions are orbifolded such that they reduce the gauge symmetry directly to the SM one. At low energies, only the SM field content remains with viable unified Yukawa couplings. Full unification can be achieved at energies as low as 10⁶ \rmGeV with controlled proton decay.
