  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. The top mass arises
dynamically from the electroweak breaking condensate. The other standard model
fermion masses arise naturally from higher-dimension operators, and the fermion
mass hierarchies and flavor structure can be explained from the localization of
the zero-modes in the extra dimension. If any other contributions to the radion
potential except those directly related with electroweak symmetry breaking are
engineered to be suppressed, the KK scale is predicted to be about two orders
of magnitude above the electroweak scale rendering the model easily consistent
with electroweak precision data. The model predicts a heavy (composite) Higgs
with a mass of about 500 GeV and standard-model-like properties, and a
vector-like quark with non-negligible mixing with the top quark and mass in the
1.6 - 2.9 TeV range. Both can be within the reach of the LHC. It also predicts
a radion with a mass of a few GeV that is very weakly coupled to standard model
matter.
