TL;DR
This paper investigates radion stabilization in 5D conformal supergravity compactified on an orbifold, exploring effects of various couplings and quantum corrections, and identifying new stable and metastable Minkowski vacua.
Contribution
It provides a detailed analysis of radion stabilization mechanisms in 5D SUGRA, including one-loop and non-perturbative effects, with new examples of stable and metastable vacua.
Findings
Radion stabilization achieved in non-SUSY and SUSY-preserving Minkowski vacua.
Quantum corrections and boundary couplings significantly influence stabilization.
New stable and metastable vacua identified in the model.
Abstract
We present a detailed study of radion stabilization within 5D conformal SUGRA compactified on an 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.
