For a 5D Standard Model propagating in an AdS background with an IR localized
Higgs, compatibility of bulk KK gauge modes with EWPT yields a
phenomenologically unappealing KK spectrum (m > 12.5 TeV) and leads to a
"little hierarchy problem". For a bulk Higgs the solution to the hierarchy
problem reduces the previous bound only by sqrt(3). As a way out, models with
an enhanced bulk gauge symmetry SU(2)_R x U(1)_(B-L) were proposed. In this
note we describe a much simpler (5D Standard) Model, where introduction of an
enlarged gauge symmetry is no longer required. It is based on a warped
gravitational background which departs from AdS at the IR brane and a bulk
propagating Higgs. The model is consistent with EWPT for a range of KK masses
within the LHC reach.Comment: 7 pages, 3 figures. Based on talk given by M. Quiros at the Workshop
