Warped 5D Standard Model Consistent with EWPT

By Joan A. Cabrer, Gero von Gersdorff and Mariano Quiros


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 on the Standard Model and Beyond - Cosmology, Corfu Summer Institute, Greece, August 29 - September 5, 201
