Standard(-like) Model from an image Grand Unified Theory in six-dimensions with image extra-space Original Research Article

We analyze a gauge-Higgs unification model which is based on a gauge theory defined on a six-dimensional spacetime with an image extra-space. We impose a symmetry condition for a gauge field and non-trivial boundary conditions of the image. We provide the scheme for constructing a four-dimensional theory from the six-dimensional gauge theory under these conditions. We then construct a concrete model based on an image gauge theory with fermions which lie in a 32 representation of image, under the scheme. This model leads to a Standard Model(-like) gauge theory which has gauge symmetry image and one generation of SM fermions, in four-dimensions. The Higgs sector of the model is also analyzed, and it is shown that the electroweak symmetry breaking and the prediction of W-boson and Higgs-boson masses are obtained.
