Abstract

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 (h$_1$) could lie in the 1-2 TeV range in the models with a bulk custodial symmetry. We find that the h$_1$ is gaugephobic and decays dominantly into a $ t\overlinet $ pair. We also discuss the search strategy for h$_1$ decaying to $ t\overlinet $ at the Large Hadron Collider. We used substructure tools to suppress the large QCD background associated with this channel. We find that h$_1$ can be probed at the LHC run-2 with an integrated luminosity of 300 fb$^−1$.
