The absence, so far, of any graviton signatures at the LHC imposes severeconstraints on the Randall-Sundrum scenario. Although a generalization tohigher dimensions with nested warpings has been shown to avoid theseconstraints, apart from incorporating several other phenomenologicallyinteresting features, moduli stabilization in such models has been an openquestion. We demonstrate here how both the moduli involved can be stabilized,employing slightly different mechanisms for the two branches of the theory.This also offers a dynamical mechanism to generate and stabilize the scale forthe Universal Extra Dimensions, another long-standing issue.

Stabilization of moduli in spacetime with nested warping and the UED
