Abstract

V originále

We propose a minimal and self-contained model in non-compact flat five dimensions that localizes the Standard Model (SM) on a domain wall. Localization of gauge fields is achieved by condensation of the Higgs field via a Higgs-dependent gauge kinetic term in the 5D Lagrangian. The domain wall connecting vacua with unbroken gauge symmetry drives the Higgs condensation, which provides both electroweak symmetry breaking and gauge field localization at the same time. Our model predicts higher-dimensional interactions |H|^{2n}(F_{mu nu})^2 in the low-energy effective theory. This leads to two expectations: One is a new tree-level contribution to H -> gamma gamma (H -> gg) decay whose signature will be testable in future LHC experiments. The other is a finite electroweak monopole that may be accessible to the MoEDAL experiment. Interactions of the translational Nambu-Goldstone boson are shown to satisfy a low-energy theorem.
