Gauge-Higgs Unification in Higher Dimensions
The electroweak Higgs doublets are identified as components of a vector multiplet in a higher dimensional supersymmetric field theory. We construct a minimal model in 6D where the electroweak SU(2) ⊗ U(1) gauge group is extended to SU(3), and unified 6D models with the unified SU(5) gauge symmetry extended to SU(6). In these realistic theories the extended gauge group is broken by orbifold boun...
متن کاملGauge Unification in Higher Dimensions
A complete 5-dimensional SU(5) unified theory is constructed which, on compactification on the orbifold S/(Z2 ×Z ′ 2), yields the minimal supersymmetric standard model. The orbifold accomplishes SU(5) gauge symmetry breaking, doublet-triplet splitting, and a vanishing of proton decay from operators of dimension 5. Until 4d supersymmetry is broken, all proton decay from dimension 4 and dimension...
متن کاملGauge-higgs Unification in Six Dimensions
Motivated by the pressing problem of the “little hierachies”, the possibility of realizing a consistent model of Electroweak Symmetry Breaking via the so-called “Gauge-Higgs Unification Mechanism” is discussed. We identify a class of 6 dimensional SU(3) gauge models in which a single Higgs doublet originates from the internal components of the gauge fields. The Higgs mass is beautifoully predic...
متن کاملHolographic Methods and Gauge-Higgs Unification in Flat Extra Dimensions
I review the holographic techniques used to efficiently study models with Gauge-Higgs Unification (GHU) in one extra dimension. The general features of GHU models in flat extra dimensions are then reviewed, emphasizing the aspects related to electroweak symmetry breaking. Two potentially realistic models, based on SU(3) and SO(5) electroweak gauge groups, respectively, are constructed.
متن کاملUnification of Higgs and Gauge Fields in Five Dimensions
We construct realistic theories in which the Higgs fields arise from extra dimensional components of higher dimensional gauge fields. In particular, we present a minimal 5D SU(3)C×SU(3)W model and a unified 5D SU(6) model. In both cases the theory is reduced to the minimal supersymmetric standard model below the compactification scale, with the two Higgs doublets arising from the 5D gauge multi...
