Abstract

A new mechanism for the radius stabilization is proposed in a 5D super-Yang–Mills model in the warped background of AdS 5 . 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 Fayet–Iliopoulos D-term for the gauge group U(1) reveals an interesting case that the radius is stabilized at a length corresponding to an intermediate mass scale 10 11 – 13 GeV .
