“…In the case where the 4D symmetry is SO (10) Because of the bulk symmetry, the gauge couplings can be unified at grand unified scale as well as Yukawa couplings for third family. The numerical predictions are in good agreement with experimental data [17] and we have predictions for tan β and relations between threshold corrections for the supersymmetry breaking [22]. At the same time, the colored Higgs fields can be projected out by orbifold conditions.…”

“…In the context of gauge-Higgs unification, it is gauge invariance that prohibits the large supersymmetric Higgs mass. Another advantage for supersymmetric gauge-Higgs unification is the possibility that the third family Yukawa couplings might unify with gauge couplings at a grand unified scale [17,22]. Thus gauge-Higgs unification may present a new paradigm for understanding the origin of families and the structure of quark and lepton mass matrices.…”

In supersymmetric theories with extra dimensions, the Higgs and matter fields can be part of the gauge multiplet, so that the Yukawa interactions can arise from the gauge interactions. This leads to the possibility of gauge-Yukawa coupling unification, g i = y f , in the effective four dimensional theory after the initial gauge symmetry and the supersymmetry are broken upon orbifold compactification. We consider gauge-Yukawa unified models based on a variety of four dimensional symmetries, including SO(10), SU(5), Pati-Salam symmetry, trinification, and the Standard Model. Only in the case of Pati-Salam and the Standard Model symmetry, we do obtain gauge-Yukawa unification. Partial gauge-Yukawa unification is also briefly discussed.

“…The SU(4) C symmetry unifying quarks and leptons is broken down to SU(3) C ×U(1) B−L by compactifying the extra dimension, y on a S 1 /(Z 2 × Z ′ 2 ) orbifold. (The breaking of gauge symmetry via orbifold compactification is very elegant and has been extensively used in the literature to build realistic models [7][8][9][10][11][12][13][14][15][16][17][18][19][20]). The remaining symmetry, U(1) B−L × U(1) I3R in our model in four dimensions (4D) is then broken down to the SM by using appropriate Higgs multiplets.…”

The idea of unifying quarks and leptons in a gauge symmetry is very appealing.However, such an unification gives rise to leptoquark type gauge bosons for which current collider limits push their masses well beyond the TeV scale. We present a model in the framework of extra dimensions which breaks such quark-lepton unification symmetry via compactification at the TeV scale. These color triplet leptoquark gauge bosons, as well as the new quarks present in the model, can be produced at the LHC with distinctive final state signatures. These final state signals include high p T multi-jets and multi-leptons with missing energy, monojets with missing energy, as well as the heavy charged particles passing through the detectors, which we also discuss briefly. The model also has a neutral Standard Model singlet heavy lepton which is stable, and can be a possible candidate for the dark matter.

Supersymmetric gauge theories, in higher dimensions compactified in an orbifold, give a natural framework to unify the gauge bosons, Higgs fields and even the matter fields in a single multiplet of the unifying gauge symmetry. The extra dimensions and the supersymmetry are the two key ingredients for such an unification. In this work, we investigate various scenarios for the unification of the three gauge couplings, and the Yukawa couplings in the Minimal Supersymmetric Standard Model (MSSM), as well as the trilinear Higgs couplings λ and κ of the Non-Minimal Supersymmetric Standard Model (NMSSM). We present an SU(8) model in six dimensions with N = 2 supersymmetry, compactified in a T 2 /Z 6 orbifold which unifies the three gauge couplings with λ and κ of NMSSM. Then, we present an SU(9) model in 6D, which, in addition, includes partial unification of Yukawa couplings, either for the up-type (top quark and Dirac tau-neutrino) or down-type (bottom quark and tau lepton). We also study the phenomenological implications of these various unification scenarios using the appropriate renormalization group equations, and show that such unification works very well with the measured low energy values of the couplings. The predicted upper bounds for the lightest neutral Higgs boson mass in our model is higher than those in MSSM, but lower that those in the general NMSSM (where the couplings λ and κ are arbitrary). Some of the predictions of our models can be tested in the upcoming Large Hadron Collider.
