چکیده
We investigate the model of warped spatial dimension (popularly known as Randall-Sundrum model) in the light of the muon anomalous magnetic moment, aμ[= (g−2) 2 ]. Using the present theoretical value (based on standard model calculation) and the BNL measurement of muon anomalous magnetic moment, we obtain constraints on radion (required to fix the size of the extra dimension) mass mφ and radion vev 〈φ〉. We determine the beta functions β(λ) and β(gt) in the presence of radion. Using these modified beta functions and the anomaly constrained mφ and 〈φ〉 values, we find some lower bounds on higgs mass mh and compare that with the present LEP2 direct bound on mh.

Muon anomaly and a lower bound on higgs mass due to a light stabilized radion in the Randall-Sundrum model
We investigate the Randall-Sundrum model (of Type-I) in the light of muon anomalous magnetic moment, aμ[= (g−2) 2 ]. Using the present theoretical value (based on standard model calculation) of aμ and the experimental result reported by the BNL group, we obtain constraints on radion (required to fix the size of the fifth(extra) warped spatial dimension ) mass mφ and radion vev 〈φ〉. The beta fun...
متن کاملTestable (g − 2)μ contribution due to a light stabilized radion in the Randall-Sundrum model
In this paper we calculate the (g − 2)μ contribution due to a light stabilized radion using the radion couplings both to the kinetic energy and the mass term of the muon. We find that the (g − 2)μ contribution due to radion diverges logarithmically with the cut off. We then show that the bound from precision EW data on radion phenomenology allows a sizable shift in the radion mediated muon anom...
متن کاملRadion Phenomenology in the Randall Sundrum Scenario
Phenomenology of a radion (φ) in the Randall-Sundrum scenario is discussed. The radion couples to the trace of energy momentum tensor of the standard model with a strength suppressed only by a new scale (Λφ) which is an order of the electroweak scale. In particular, the effective coupling of a radion to two gluons is enhanced due to the trace anomaly of QCD. Therefore, its production cross sect...
متن کاملImplications of radion-higgs couplings for high energy scattering in the Randall-Sundrum model
In this report we derive the couplings of the Randall-Sundrum radion to the standard model higgs boson. We then use these couplings to determine the J=0 partial wave amplitude for the process hh → hφ. We find that at very high energies (i.e. s ≫ mh, mφ) the s wave partial wave unitarity is violated if mh > mc ≈ √ 16π〈φ〉v where 〈φ〉 is the radion vev. Interestingly this bound is independent of th...
متن کاملUnitarity Bound on the Radion Mass in the Randall-sundrum Model
In this paper we derive an upper bound on the mass of the Randall-Sundrum radion by imposing the unitarity condition on the tree level amplitude for the process W L W − L → hφ. We find that at sufficiently high energies (i.e s ≫ mφ, mh, mw ) the J=0 partial wave amplitude could violate unitarity if mφ > mc ≈ √ 16π〈φ〉mw g where 〈φ〉 is the radion vev. Interestingly this bound on mφ is independent...
