Description
We analyze a gauge-Higgs unification model which is based on
a gauge theory defined on a six-dimensional spacetime with an $S^2$ extra-space.
We impose a symmetry condition for a gauge field and non-trivial boundary conditions of the $S^2$.
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 SO(12) gauge theory
with fermions which lie in a 32 representation of SO(12), under the scheme.
This model leads to a Standard-Model(-like) gauge theory which has gauge
symmetry SU(3) $\times$ SU(2)$_L$ $\times$ U(1)$_Y$($\times$ U(1)$^2$)
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.
