Radion stabilization in 5D SUGRA

We present a detailed study of radion stabilization within 5D conformal SUGRA compactified on an S(1)/Z2 orbifold. We use an effective 4D superfield description developed in our previous work. The effects of tree level bulk and boundary couplings, and in particular of one-loop contributions and of a non-perturbative correction on the radion stabilization are investigated. We find new examples of radion stabilization in non SUSY and (meta-stable) SUSY preserving Minkowski vacua.
