The bulk Higgs in the Deformed RS Model

Abstract

The Randall-Sundrum model with a deformed metric can generate light Kaluza-Klein (KK) Higgs modes consistent with the electroweak precision analysis for a certain range of parameters. The first KK mode of the Higgs (h1) in such a model could lie in the mass range varying from 800 GeV to 1.3 TeV. We find that the h1 is gaugephobic and decays dominantly into a tt pair. The search strategy for h1 decaying to tt at the Large Hadron Collider (LHC) in this low mass range has been studies. We have used substructure tools to suppress the large QCD background associated with this channel. We find that h1 can be probed at the LHC.
