Radion and Higgs mixing at the LHC
We study the resonance production of radions and Higgs via gluon-gluon fusion in the Randall-Sundrum model with Higgs-curvature mixing at the LHC. We find that radion can be detected both in mixed (with Higgs boson) and unmixed case if the radion vacuum expectation value Λφ is around 1 TeV. The Λφ ∼ 10 TeV case is also promising for certain values of mixing parameters and radion masses. The mix...
متن کاملEffects on Higgs Boson Properties From Radion Mixing
We discuss how mixing between the Standard Model Higgs boson, h, and the radion of the Randall-Sundrum model can lead to significant shifts in the expected properties of the Higgs boson. In particular we show that the total and partial decay widths of the Higgs, as well as the h → gg branching fraction, can be substantially altered from their SM expectations, while the remaining branching fract...
متن کاملProbing the Radion-Higgs mixing at hadronic colliders
Abstract In the Randall-Sundrum model, the radion-Higgs mixing is weakly suppressed by the effective electroweak scale. One of its novel features would be a sizable three-point vertex of h (n) μν -h-φ. We explored the potential of the Fermilab Tevatron and the CERN LHC in probing the radion-Higgs mixing via the associated production of the radion with the Higgs boson. The observation of the rar...

Abstract In the Randall-Sundrum model, the radion-Higgs mixing is weakly suppressed by the effective electroweak scale. A novel feature of the gravity-scalar mixing would be a sizable three-point vertex of h (n) μν -h-φ. We explore the potential of photon colliders, achieved by the laser backscattering technique, in probing the radion-Higgs mixing via the associated production of the radion wit...
