title: Could the excess seen at 124-126 GeV be due to the Randall-Sundrum radion?
abstract: Current Higgs boson searches in various channels at the LHC point to an excess at around 124-126 GeV due to a possibly standard-model-like Higgs boson. If one examines more closely the channels (γγ, WW(*), and ZZ(*)) that have excess, this "Higgs boson" may be the Randall-Sundrum radion ϕ. Because of the trace anomaly, the radion has stronger couplings to the photon and gluon pairs. Thus, it will enhance the production rates into gg and γγ, while those for WW(*), ZZ(*), and b ̅b are reduced relative to their standard model values. We show that it can match well with the data from CMS for m(ϕ)=124  GeV, and the required scale Λ(ϕ)∼<ϕ> is about 0.68 TeV.
