Abstract

We study constraints on the radion mass and couplings in the Randall–Sundrum model from the recent LHC data on the Standard Model (SM) Higgs boson searches. When the radion is heavy enough so that it can decay into a pair of on-shell Z-bosons, we find that the ZZ channel gives a stringent constraint. For example, if the radion mass mϕ is 200 GeV, the scale Λϕ which characterizes the interactions of the radion with the SM fields must be larger than 5 TeV. Even for mϕ = 1 TeV, we find that the lower bound on Λϕ is 2 TeV.
