We study a mechanism of symmetry transition upon compactification of a 5-dimensional field theory on $S^1/Z_2$. The transition occurs unless all components in a multiplet of a symmetry group have a common $Z_2$ parity on $S^1/Z_2$. This mechanism is applied to a reduction of SU(5) gauge symmetry in grand unified theory, and phenomenological implications are discussed.

The Hosotani Mechanism in Bulk Gauge Theories with an Orbifold Extra Space S 1 /Z 2
We pursue the possibility of the scenario in which the Higgs field is identified with the extra-space component of a bulk gauge field. The space–time we take is M4 ⊗ S1/Z2. We show that a nontrivialExpand
Classification of Standard Model Particles in $E_6$ Orbifold Grand Unified Theories
We classify the standard model fermions, which originate from bulk fields of the 27 or representation after orbifold breaking, in E6 grand unified theories on five- or six-dimensional space–time,Expand
Orbifold breaking of 3-3-1 model
Abstract We study the five-dimensional SU (3) c × SU (3) L × U (1) X gauge theory (3–3–1 model) in which the gauge symmetry is broken down through orbifold compactification to four dimensions. TheExpand
Predictions of SU(9) orbifold family unification
Abstract We study predictions of orbifold family unification models with SU ( 9 ) gauge group on a six-dimensional space–time including the orbifold T 2 / Z 2 , and obtain relations among sfermionExpand
Dynamical rearrangement of gauge symmetry on the orbifold S1/Z2
Abstract Gauge theory defined on the orbifold M 4 ×( S 1 / Z 2 ) is investigated from the viewpoint of the Hosotani mechanism. Rearrangement of gauge symmetry takes place due to the dynamics ofExpand
Orbifold family unification on six dimensions
We study the possibility of family unification on the basis of SU(N) gauge theory on the 6-dimensional space-time, M 4 ×T 2 /ZN. We obtain enormous numbers of models with three families of SU(5)Expand
String-Inspired Special Grand Unification
We discuss a grand unified theory (GUT) based on an $SO(32)$ GUT gauge group broken to its subgroups including a special subgroup. In the $SO(32)$ GUT on six-dimensional (6D) orbifold spaceExpand
Vacuum structure in 5D SO(10) GUT on S1/Z2
Abstract We study the vacuum structure in 5D SO ( 10 ) grand unified theory (GUT) compactified on S 1 / Z 2 orbifold, where SO ( 10 ) is broken into SU ( 3 ) × SU ( 2 ) × U ( 1 ) 2 through theExpand
The standard model gauge symmetry from higher-rank unified groups in grand gauge-Higgs unification models
A bstractWe study grand unified models in the five-dimensional space-time where the extra dimension is compactified on S1/ℤ2. The spontaneous breaking of unified gauge symmetries is achieved viaExpand
Non-perturbative gauge-Higgs unification: symmetries and order parameters
A bstractWe consider pure SU(N) gauge theories defined on an orbifold lattice, analogous to the S1/$ {{\mathbb{Z}}_2} $ gauge theory orbifolds of the continuum, which according to the perturbativeExpand
