TL;DR
This paper investigates quantum effects on the radion superfield in a supersymmetric Randall-Sundrum model, demonstrating how one-loop corrections stabilize all moduli and break supersymmetry.
Contribution
It provides a perturbative mechanism for moduli stabilization and supersymmetry breaking via one-loop effective potential analysis.
Findings
Classical stabilization of brane distance
Quantum corrections generate a potential for the graviphoton VEV
All moduli are stabilized perturbatively
Abstract
We study the one loop effective potential for the radion superfield in the supersymmetric Randall-Sundrum scenario with detuned brane tensions. At the classical level the distance between the branes is stabilized while the VEV of the fifth component of the graviphoton is a flat direction which breaks supersymmetry. At the quantum level a potential is generated. This leads to a toy model of a supersymmetric compactification with all the moduli stabilized perturbatively.
