Warped Supersymmetric Radius Stabilization
نویسندگان
چکیده
A simple model of extra-dimensional radius stabilization in a supersymmetric Randall-Sundrum model is presented. In our model, we introduce only a bulk hypermultiplet and source terms on each boundary branes. With an appropriate choice of model parameters, we find that the radius can be stabilized by supersymmetric vacuum conditions. Since the radion mass can be much larger than the gravitino mass and the supersymmetry breaking scale, the radius stability is ensured even with the supersymmetry breaking. We find a parameter region where unwanted scalar masses induced by quantum corrections through the bulk hypermultiplet and a bulk gravity multiplet are suppressed and the anomaly mediation contributions dominate.

Supersymmetric Radius Stabilization in Warped Extra Dimensions
We propose a simple model of extra-dimensional radius stabilization in a supersymmetric Randall-Sundrum model. In our model, we introduce only a bulk hypermultiplet and source terms (tadpole terms) on each boundary branes. With appropriate choice of model parameters, we find that the radius can be stabilized by supersymmetric vacuum conditions. Since the radion mass can be much larger than the ...
متن کاملA New Mechanism for Radius Stabilization in Warped Supersymmetry
A new mechanism for the radius stabilization is proposed in a 5D super-YangMills model in the warped background of AdS5. Dominant 1-loop contribution to the supersymmetric 4D effective potential is estimated to depend on the radion. The minimization of the effective potential incorporating the tree potential and a FayetIliopoulos D-term for the gauge group U(1) reveals an interesting case that ...
متن کاملHierarchy Stabilization in Warped Supersymmetry
We show that exponentially large warp factor hierarchies can be dynamically generated in supersymmetric compactifications. The compactification we consider is the supersymmetric extension of the Randall–Sundrum model. The crucial issue is the stabilization of the radius modulus for large warp factor. The stabilization sector we employ is very simple, consisting of two pure Yang–Mills sectors, o...
متن کاملGravitational Radius Stabilization in Supersymmetric Warped Compactification
We examine the possibility of the extra dimensional radius stabilization with only the gravity multiplet in the bulk and some couplings at orbifold fixed points in a supersymmetric Randall-Sundrum model. Unfortunately, we find that the radius cannot be stabilized in all the cases we consider. Depending on parameters in the model, the fifth dimension collapses or its radius goes to infinity. Whi...
متن کاملOn Supersymmetric D7-branes in the Warped Deformed Conifold
We study the supersymmetric properties of D7-branes in the warped deformed conifold. We consider the κ-symmetry conditions on D7-branes in this specific warped background, taking into account the background NS-NS 2-form flux. While any holomorphic embedding defines a supersymmetric D7-brane in the absence of background H-flux, most of the D7-brane embeddings considered in the literature do not ...
