abstract = {We consider a warped  ve-dimensional model with an ultraviolet (UV) brane
and, on top of the Standard Model isolated modes, continua of KK modes with different
mass gaps for all particles: gauge bosons, fermions, graviton, radion and Higgs boson. The
model can be considered as a modelization in  ve dimensions of gapped unparticles. The
 ve dimensional metric has a singularity, at a finite (infinite) value of the proper (conformal)
coordinate, which is admissible as it supports finite temperature in the form of a black
hole horizon. An infrared (IR) brane, with particular jumping conditions, is introduced
to trigger correct electroweak breaking. The gravitational metric is AdS5 near the UV
brane, to solve the hierarchy problem with a fundamental Planck scale, and linear, in
conformal coordinates, near the IR, as in the linear dilaton and  ve-dimensional clockwork
models. The branes, and singularity, distances are  fixed, à la Goldberger-Wise, by a bulk
scalar  field with brane potentials explicitly breaking the conformal symmetry. The bosonic
continuum of KK modes with the smallest mass gap are those of gauge bosons, and so they
are the most likely produced at the LHC. Mass gaps of the continuum of KK fermions
do depend on their localization in the extra dimension. We have computed the spectral
functions, and arbitrary Green's functions, and shown how they can modify some Standard
Model processes.},
