Abstract 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 KK < 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 ∼ 1 \over 2 . As a way out, models with an enhanced bulk gauge symmetry SU(2) R × 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.
