Abstract
We examine an extension of the Standard Model which results from a 10D, \( \mathcal{N} \) = 1, E8 gauge theory. The theory is dimensionally reduced over a M4 × B0/Z3 space, where B0 is the nearly-Kähler manifold SU(3)/U(1) × U(1) and Z3 is a freely acting discrete group on B0 that triggers a Wilson flux breaking, leading to an \( \mathcal{N} \) = 1, SU(3)3 × U(1)2 effective theory in 4D. At lower energies we are left with the Split NMSSM. Its 2-loop analysis yields third generation quark and light Higgs masses within the experimental limits and predicts a neutralino LSP mass < 800 GeV.
