Query: Higgs Bosons in Extra Dimensions   In this paper, motivated by the recent discovery of a Higgs-like boson at the
LHC with a mass m_H\simeq 126 GeV, we review different models where the
hierarchy problem is solved by means of a warped extra dimension. In the
Randall-Sundrum model electroweak observables provide very strong bounds on the
mass of KK modes which motivates extensions to overcome this problem. Two
extensions are briefly discussed. One particular extension is based on the
deformation of the metric such that it strongly departs from the AdS_5
structure in the IR region while it goes asymptotically to AdS_5 in the UV
brane. This model has the IR brane close to a naked metric singularity (which
is outside the physical interval) characteristic of soft-walls constructions.
The proximity of the singularity provides a strong wave-function
renormalization for the Higgs field which suppresses the T and S parameters.
The second class of considered extensions are based on the introduction of an
extra gauge group in the bulk such that the custodial SU(2)_R symmetry is
gauged and protects the T parameter. By further enlarging the bulk gauge
symmetry one can find models where the Higgs is identified with the fifth
component of gauge fields and for which the Higgs potential, along with the
Higgs mass, can be dynamically determined by the Coleman-Weinberg mechanism.
