"Brane localized energy density" stabilizes the modulus in higher dimensional warped spacetime

Abstract: We consider a five dimensional AdS spacetime with two 3-brane scenario where the hidden brane contains a certain amount of positive constant energy density. In this model, we examine the possibility of modulus stabilization. Our result reveals that the non-zero value of "hidden brane energy density" is sufficient to stabilize the two brane system. Moreover we scan the parametric space for which the modulus (or radion) is going to be stabilized without sacrificing the conditions necessary to solve the gauge hierarchy problem. Finally we obtain the mass and coupling parameters of radion field in this higher dimensional braneworld scenario.
