Gauge Coupling Unification with Large Extra Dimensions
We make a detailed study of the unification of gauge couplings in MSSM with large extra dimensions. We find some scenarios where unification can be achieved (with α3 (MZ) within 1σ of the experimental value) with both the compactification scale and the SUSY breaking scale in the few TeV range. No enlargement of the gauge group or particle content is needed. One particularly interesting scenario...
متن کاملGauge Coupling Unification with Extra Dimensions and Gravitational Scale Effects
We study gauge coupling unification in the presence of extra dimensions compactified at a few TeV. Achieving unification requires a large number of gauge boson Kaluza-Klein excitations lighter than the string scale, such that the higher-dimensional gauge couplings are O(1) in string scale units. Corrections to the gauge couplings from two or more loops are about 10% or larger, hence string (or ...
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 Gauge, Higgs and Matter in Extra Dimensions
We consider the unification of gauge, Higgs as well as the matter fields in a 6D N= 2 supersymmetric SU(8) gauge theory. The gauge symmetry SU(8) is broken down to SU(4)× SU(2)L × SU(2)R × U(1) in 4D through T 2/Z6 orbifold compactification, and the theory is reduced to 4D N = 1 supersymmetric Pati-Salam model. The electroweak Higgs fields as well as the third family of fermions are unified in ...
متن کاملHiggs Boson Mass From Gauge-Higgs Unification
In certain five dimensional gauge theories the Standard Model Higgs doublet is identified, after compactification on the orbifold S/Z2, with the zero mode of the fifth component of the gauge field. An effective potential for the Higgs field is generated via quantum corrections, triggered by the breaking of the underlying gauge symmetry through boundary conditions. The quartic Higgs coupling can...
