The Planck Scale from Top Condensation

Understand

We propose a scenario in which the Planck scale is dynamically linked to the electroweak scale induced by top condensation.

• The standard model field content, without the Higgs, is promoted to a 5D warped background.
• There is also an additional 5D fermion with the quantum numbers of the right-handed top.
• Localization of the zero-modes leads, at low energies, to a Nambu-Jona-Lasinio model that also stabilizes the radion field dynamically thus explaining the hierarchy between the Planck scale and v_EW = 174 GeV.
