Radion stabilization in the Randall-Sundrum model with quadratic and quartic potentials

چکیده

In this report we investigate the Goldberger-Wise (GW) mechanism of radion stabilization with quartic potential on the hidden brane and quadratic potential on the visible brane. The advantage of our simplified scenario over the original GW mechanism is that the modulus potential can be evaluated for finite λv and λh. This enables us to probe how the modulus potential behaves over the entire range of λh. By staying away from the GW limit of k λvv v →0 and k λhv 2 h →0 we show that it is possible to choose the parameters of the model so that the potential exhibits a minimum at krc ≈ 12 and this adjustment does not involve any extreme fine tuning of parameters.

A Systematic Study of the Radion in the Compact Randall-sundrum Model

We systematically study the question of identification and consistent inclusion of the radion, within the Lagrangian approach, in a two brane Randall-Sundrum model. Exploiting the symmetry properties of the theory, we show how the radion can be identified unambiguously and give the action to all orders in the radion field and the metric. Using the background field method, we expand the theory t...

Detuned Randall-sundrum Model: Radion Stabilization and Supersymmetry Breaking *

In this talk I describe the low energy effective theory of the (supersymmetric) Randall-Sundrum scenario with arbitrary brane tensions. The distance between the branes is stabilized, at the classical level, by a potential for the radion field. In the supersymmetric case, supersymmetry can be broken by a VEV for the fifth-component of the graviphoton.

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...

Unitarity constraints on the stabilized Randall-Sundrum scenario

The recently proposed stabilization mechanism for the Randall-Sundrum metric gives rise to a light scalar radion, that couples to matter much as the Standard Model Higgs. The characteristic scale for these couplings is ∼ O(1 TeV). Demanding that gauge boson scattering as described by the effective low energy theory be unitary upto a given energy scale leads to significant constraints on the par...

Implications 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...
