چکیده
Stability of the Higgs mass in theories with extra dimensions † Abstract We analyze the ultraviolet stability of the Higgs mass in recently proposed Kaluza-Klein models com-pactified on S 1 /Z 2 or S 1 /(Z 2 × Z ′ 2), both at the field theory and string theory level. Fayet-Iliopoulos terms of U (1) hypercharge are shown to be of vital importance for this discussion. Models with a single Higgs doublet seem to be generically affected by quadratic divergences.

متن کاملLight Higgs Triplets in Extra Dimensions
We discuss the possibility that the Higgs triplet can be light (1TeV in the most interesting case) without contradictions with the proton stability in the context of higher dimensional theory. The proton stability is ensured by the suppression of Yukawa coupling of the Higgs triplet to the matter through its small overlap of wave functions in extra dimensions. The light Higgs triplets might be ...
متن کاملDivergences and Symmetries in Higgs-gauge Unification Theories
In theories with extra dimensions the Standard Model Higgs field can be identified with the internal components of higher-dimensional gauge fields (Higgs-gauge unification). The higherdimensional gauge symmetry prevents the Higgs mass from quadratic divergences, but at the fixed points of the orbifold this symmetry is broken and divergences can arise if U(1) subgroups are conserved. We show tha...
متن کاملThe lightest Higgs mass in supersymmetric models with extra dimensions ∗
In the four-dimensional supersymmetric standard model extended with gauge singlets the lightest Higgs boson mass, M H , has an important contribution proportional to the squared of the superpotential coupling λ of singlets to Higgs fields, λ SH 1 · H 2. The requirement of perturbativity up to the unification scale yields an upper bound on M H ∼ 140 GeV. In extensions to theories with (longitudi...
متن کاملPhenomenology of the Neutrino-Mass-Giving Higgs Triplet and the Low-Energy Seesaw Violation of Lepton Number
Small realistic Majorana neutrino masses can be generated via a Higgs triplet (ξ, ξ, ξ) without having energy scales larger than M∗ = O(1) TeV in the theory. The large effective mass scale Λ in the well-known seesaw neutrino-mass operator Λ(LLΦΦ) is naturally obtained with Λ ∼ M ∗ /μ, where μ is a small scale of lepton-number violation. In theories with large extra dimensions, the smallness of ...
