The bulk Higgs in the Deformed RS Model

Electroweak precision tests allow for lighter Kaluza–Klein (KK) Higgs modes in the deformed Randall–Sundrum (RS) model than in models with custodial symmetry. The first KK mode of the Higgs ( h1 ) in such a model could have a mass as low as 900 GeV. In this paper, we study the production of h1 and i...

description Electroweak precision tests allow for lighter Kaluza–Klein (KK) Higgs modes in the deformed Randall–Sundrum (RS) model than in models with custodial symmetry. The first KK mode of the Higgs ( h1 ) in such a model could have a mass as low as 900 GeV. In this paper, we study the production of h1 and its subsequent decay to a tt¯ pair at the Large Hadron Collider (LHC), in the context of the deformed RS model. We have performed a hadron-level Monte Carlo simulation of the signal and the relevant Standard Model background. We present strategies to effectively suppress the huge SM background and provide a signal that is tractable at the future runs of the LHC.

We have performed a hadron-level Monte Carlo simulation of the signal and the relevant Standard Model background. We present strategies to effectively suppress the huge SM background and provide a signal that is tractable at the future runs of the LHC.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 ($h_{1}$) in such a model could lie in the mass range varying from 800 GeV to 1.3 TeV. We find that the $h_{1}$ is gaugephobic and decays dominantly into a $t\bar{t}$ pair. The search strategy for $h_{1}$ decaying to $t\bar{t}$ 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 $h_{1}$ can be probed at the LHC.arXiv:1712.04966CERN-TH-2017-260TIFR/TH/17-44TIFR-TH-17-44oai:cds.cern.ch:22986362017-12-13
