The significant heavy threshold effect is found in the minimal supersymmetric $\mathrm{SU}(5)$ model with two adjoint scalars, one of which is interpreted as a massive string mode largely decoupled from the lower-energy particle spectra. This threshold related with the generic mass splitting of the basic adjoint moduli is shown to alter properly the running of gauge couplings, thus giving a natural solution to the string-scale grand unification. The further symmetry condition of the (top-bottom… Expand
Gauge-Higgs unification in the left–right model
Abstract We construct a supersymmetric left–right model in four dimension with gauge-Higgs unification starting from a SU (3) c × SU (4) w × U (1) B − L gauge symmetry in five dimension. The modelExpand
Yukawa couplings in a model with gauge, Higgs and matter unification
Abstract We discuss how unification of the gauge, Higgs and (three chiral family) matter superfields can be realized from the compactification of a six-dimensional supersymmetric SU ( 8 ) gaugeExpand
Resurrecting the minimal renormalizable supersymmetric SU(5) model
A bstractIt is a well-known fact that the minimal renormalizable supersymmetric SU(5) model is ruled out assuming superpartner masses of the order of a few TeV. Giving up this constraint and assumingExpand
Challenging the minimal supersymmetric SU(5) model
We review the main constraints on the parameter space of the minimal renormalizable supersymmetric SU(5) grand unified theory. They consist of the Higgs mass, proton decay, electroweak symmetryExpand
Realistic fermion masses and nucleon decay rates in supersymmetric SU(5) with vectorlike matter
We show that by adding a vectorlike 5 þ � 5 pair of matter fields to the spectrum of the minimal renormalizable supersymmetric SUð5Þ theory the wrong relations for fermion masses can be corrected,Expand
Test of gauge-Yukawa unification
Abstract Recently it has been proposed that, in the framework of quantum field theory, both the Standard Model gauge and Yukawa interactions arise from a single gauge interaction in higher dimensionsExpand
Higgs and sparticle spectroscopy with Gauge-Yukawa unification
We explore the Higgs and sparticle spectroscopy of supersymmetric SU(4)c × SU(2)L × SU(2)R models in which the three MSSM gauge couplings and third family (t-b-τ) Yukawa couplings are all unified atExpand
Supersymmetry and Unification: Heavy Top Was the Key §

Realistic Supersymmetric SU(6)
Abstract We present an example of SUSY SU (6) GUT, which predicts an excellent value for α s ( M Z )(≃0.119), in comparison with the value α s 0 ( M Z )≃0.126 of minimal SUSY SU (5). A crucial roleExpand
Threshold corrections to dimension-six proton decay operators in non-minimal SUSY SU(5) GUTs
Abstract We calculate the high and low scale threshold corrections to the D = 6 proton decay mode in supersymmetric S U ( 5 ) grand unified theories with higher-dimensional representation HiggsExpand
