Gauge symmetry breaking from extra space $S^1/Z_2$

  title={Gauge symmetry breaking from extra space \$S^1/Z\_2\$},
  author={Y. Kawamura},
We study a mechanism of symmetry transition upon compactification of 5-dimensional field theory on S/Z2. The transition happens unless all components in a multiplet of a symmetry group have a common Z2 parity on S /Z2. This mechanism is applied to a breakdown of SU(5) gauge symmetry in grand unified theory and phenomenological implications are discussed. ∗e-mail:

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
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
Special Grand Unification
We discuss new-type grand unified theories based on grand unified groups broken to their special subgroups as well as their regular subgroups. In the framework, when we construct four-dimensionalExpand
Scherk-Schwarz orbifolds at the LHC
We examine orbifold theories of grand unification with Scherk-Schwarz twisting, performing a renormalization group analysis and applying low energy experimental constraints. We rule out the minimalExpand
General gauge and anomaly mediated supersymmetry breaking in grand unified theories with vector-like particles
In Grand Unified Theories (GUTs) from orbifold and various string constructions the generic vector-like particles do not need to form complete SU(5) or SO(10) representations. To realize themExpand
TeV scale 5D SU(3)W unification and the fixed point anomaly cancellation with chiral split multiplets
A possibility of 5D gauge unification of SU(2)L × U(1)Y in SU(3)W is examined. The orbifold compactification allows fixed points where SU(2)L × U(1)Y representations can be assigned. We present a fewExpand
Fermion families and soft supersymmetry breaking from flux in six dimensions
In this thesis, we study compactifications from six to four dimensions on the orbifold T2/Z2. By choosing this simple famework, we are able to study effects generically present in compactificationsExpand
Spontaneous breaking of the C , P , and rotational symmetries by topological defects in extra two dimensions
We formulate models of complex scalar fields in the space-time that has a twodimensional sphere as extra dimensions. The two-sphere S is assumed to have the Dirac-Wu-Yang monopole as a backgroundExpand
Is Symmetry Breaking into Special Subgroup Special
The purpose of this paper is to show that the symmetry breaking into special subgroups is not special at all, contrary to the usual wisdom. To demonstrate this explicitly, we examine dynamicalExpand

The mass spectra of the standard model particles are reproduced in the $SO(11)$ gauge-Higgs grand unification in the six-dimensional warped space without introducing exotic light fermions. LightExpand
