Early indications from the LHC for the observed scalar boson imply properties close to the Standard Model Higgs, putting considerable constraints on TeV scale new physics scenarios. In this letter we consider flat extra dimensional scenarios with the fifth spatial dimension compactified on an S^1/Z_2 orbifold. We find in the minimal model the experimentally preferred effective Higgs couplings to gluon and photon at 95% confidence level disfavor the New Physics scale below 1.3 TeV. We demonstrate that a generalization of these models to include brane localized kinetic terms can relieve the tension to accommodate scales as low as 0.4 TeV.

  1. The Two Scales of New Physics in Loop-Induced Higgs Couplings

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A deviation in the loop-induced Higgs couplings hgg, hγγ, or hZγ caused solely by new vectorlike fermions implies an upper bound on the mass scale of new bosons needed to restore perturbativity and vacuum stability.

  2. Belle II Constraints on the Non-Minimal Universal Extra Dimensional Model

    hep-ph 2025-09 unverdicted novelty 5.0 of 10

    Belle II data on the rare B decay constrains the non-minimal UED model to require the inverse compactification radius to be at least ~900 GeV, while the minimal version yields no bound.
