Constraints on radion in a warped extra dimension model from Higgs boson
searches at the LHC    [PDF]

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 m_\phi is 200 GeV, the scale \Lambda_\phi which characterizes the interactions of the radion with the SM fields must be larger than 5 TeV. Even for m_\phi=1 TeV, we find that the lower bound on \Lambda_\phi is 2 TeV.
