The radion contribution to the weak mixing angle
نویسندگان
چکیده
In the Randall-Sundrum (RS) compactification, the gap between two branes is stabilized by the vacuum expectation value of a scalar field called radion, φ. This radion behaves like a weak interaction singlet scalar field, coupling to matter through the trace of the energy momentum tensor. We find that it can induce a sizable correction to the weak mixing angle if the vacuum expectation value and the mass of the radion is around TeV. We also comment on the contribution to the KL −KS mass difference and to (g − 2)μ. PACS: 11.25.Mj, 12.10.Dm, 98.80.Cq, 04.50.+h (

Radion effects on unitarity in gauge-boson scattering
The scalar field associated with fluctuations in the positions of the two branes, the “radion”, plays an important role determining the cosmology and collider phenomenology of the Randall-Sundrum solution to the hierarchy problem. It is now well known that the radion mass is of order the weak scale, and that its couplings to standard model fields are order O(TeV) to the trace of the energy mome...
متن کاملRadion 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 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...
متن کاملρ parameter constraints on radion phenomenology and a lower bound on Higgs mass
In this paper we determine the contribution of a light stabilized radion to the weak isospin violating ρ parameter by using an ultraviolet momentum cut off as the regulator. The LEP1 bound on ρ is then used to derive constraints on the radion mass mφ and its vev 〈φ〉. Finally by using the beta function of the higgs self coupling we have determined a lower bound on the higgs mass from the rho par...
