image GUT breaking on a projective plane Original Research Article

We consider a 6-dimensional supersymmetric image gauge theory and compactify two extra-dimensions on a multiply-connected manifold with non-trivial topology. The image is broken down to the Standard Model gauge groups in two steps by an orbifold projection, followed by a Wilson line. The Higgs doublets of the low energy electroweak theory come from a chiral adjoint of image. We thus have gauge-Higgs unification. The three families of the Standard Model can either be located in the 6D bulk or at 4D image supersymmetric fixed points.
