Higgs Boson Mass From Orbifold GUTs
We consider a class of seven-dimensional N = 1 supersymmetric orbifold GUTs in which the Standard Model (SM) gauge couplings and one of the Yukawa couplings (top quark, bottom quark or tau lepton) are unified, without low energy supersymmetry, at MGUT ≃ 4× 10 GeV. With gauge-top quark Yukawa coupling unification the SM Higgs boson mass is estimated to be 135± 6 GeV, which increases to 144± 4 Ge...
متن کاملHiggs Boson Mass from Orbifold GUTs with Split Supersymmetry
We consider orbifold GUTs with N = 1 supersymmetry in which the Standard Model (SM) gauge couplings are unified at MGUT ≃ 2×1016 GeV with one of the third family (charged) Yukawa couplings. With split supersymmetry the SM Higgs mass is estimated to be 131±10 GeV for gauge-top quark Yukawa unification, which increases to 146± 8 GeV for gauge-bottom quark (or gauge-tau lepton) Yukawa unification....
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...
متن کاملHiggs–Matter Splitting in Quasi–Realistic Orbifold String GUTs
E6 grand unification combines the Standard Model matter and Higgs states in the single 27 representation. I discuss how the E6 structure underlies the quasi–realistic free fermion heterotic–string models. E6 → SO(10) × U(1) breaking is obtained by a GSO phase in the N = 1 partition function. The equivalence of this symmetry breaking phase with a particular choice of a boundary condition basis v...
متن کاملFlavor Symmetry in Gauge-Higgs-Matter Unified Orbifold GUTs
We construct an orbifold model in which all the standard model particles are unified in a gauge multiplet in higher dimensional supersymmetric gauge theory. We find that a flavor symmetry has to remain in four dimensions due to the discrete charge conservation for orbifold conditions if the colored Higgs components in the gauge multiplet are projected out. When the flavor symmetry originates fr...
