On Moduli Stabilization Scheme in Type IIB Flux Compactifications
Abstract
Description
We revisit the two-stage procedure for moduli stabilization in Type IIB orientifolds at light Kähler-modulus limit. In view of the necessity to keep the Kähler geometry structure of the moduli space during the stabilization, we define a holomorphic quantity called effective superpotential. The KKLT superpotential as well as the superpotential proposed by Villadoro and Zwirner are then examined with respect to this holomorphic effective superpotential. The mechanism is also illustrated with a simple toy model of one complex structure modulus.
