A Higgs in the warped bulk and LHC signals

Warped models with the Higgs in the bulk can generate light Kaluza-Klein (KK) Higgs modes consistent with the electroweak precision analysis. The first KK mode of the Higgs (h1) could lie in the 1-2 TeV range in the models with a bulk custodial symmetry. We find that the h1 is gaugephobic and decays dominantly into a tt¯\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ t\overline{t} $$\end{document} pair.

We used substructure tools to suppress the large QCD background associated with this channel. We find that h1 can be probed at the LHC run-2 with an integrated luminosity of 300 fb−1.
