Electroweak Breaking on a Soft Wall

Understand

We extend the 5D gauge-higgs scenario to the soft-wall framework where the IR brane is replaced by a smoothly decaying warp factor.

• The electroweak symmetry of the Standard Model is embedded in a larger symmetry group whose gauge bosons propagate in the bulk of a warped fifth dimension.
• This gauge symmetry is partly broken by UV boundary conditions and by a condensate of a bulk scalar field.
• The Higgs boson lives partly in the 5th component of the gauge field, and partly in the the bulk scalar.
