Abstract

In the Randall-Sundrum model, radion-Higgs mixing is weakly suppressed by the effective electroweak scale. One of its novel features is a sizable three-point vertex among the Kaluza-Klein (KK) graviton, Higgs boson, and radion. We explore the potential of the Fermilab Tevatron and the CERN LHC in probing radion-Higgs mixing via the associated production of the radion with the Higgs boson. The observation of the rare decay of the KK gravitons into the radion and Higgs boson is then the direct and exclusive signal of radion-Higgs mixing. We also study all the partial decay widths of the KK gravitons in the presence of radion-Higgs mixing and find that if the mixing parameter is of the order of 1, the decay rate into a radion and a Higgs boson becomes as large as that into a Higgs boson pair, with the branching ratio of the order of [Formula Presented].
