Description
A mini-realistic brane-world scenario with a single domain wall in five-dimensional spacetime is presented. The brane is modeled via a topological soliton (domain wall), which exhibits a phase transition. At the critical point, the Higgs field condenses on the brane and i) breaks spontaneously electroweak symmetry, ii) localizes gauge fields, iii) gives mass to fermions in the standard way. All this is achieved at the electroweak scale, protected from extra-dimensional scale by a large gap. There are two unexpected and inherent bonuses to this model: first, a tree level signal of new physics in $H \to \gamma\gamma$ decay channel and, second, a finite mass electroweak monopole.
