Aspects of an N=1 split-like supersymmetric model resulting from the dimensional reduction of an N=1, 10D, E(8) gauge theory over a modified flag manifold
November 21, 2022
We review a supersymmetric extension of the Standard Model which originates from a 10D, N=1, E(8) gauge theory. The original theory is dimensionally reduced over the SU(3)/U(1)xU(1)xZ(3) space and, after making use of the Wilson breaking mechanism, the resulting 4D theory is an N=1, SU(3)^3xU(1)^2 Grand Unified Theory. Below the unification scale the remaining model is viewed as a split-like supersymmetric version of the Standard Model with two global $U(1)$s. The unification scale is predicted at ~10^16 GeV, the model is proton-decay safe and the lightest supersymmetric particles acquire masses at the region of a few TeV.
