Abstract
We find IIb compactifications on Calabi-Yau orientifolds in which all Kahler moduli are stabilized, along lines suggested by Kachru, Kallosh, Linde and Trivedi.
Highlights
The problem of stabilizing moduli in superstring compactification has seen much recent progress
A benchmark in this progress is the work of Kachru, Kallosh, Linde and Trivedi [1], which builds on many works on Calabi-Yau compactification, flux compactification and other aspects of string compactification to propose a way to construct N = 1 and non-supersymmetric vacua with all moduli stabilized in a controlled regime
An important recent work in this direction is that of Kachru, Kallosh, Linde and Trivedi [1], who argue that metastable de Sitter vacua with all moduli stabilized can be constructed in type IIb string theory, at least in an effective potential framework
Summary
The problem of stabilizing moduli in superstring compactification has seen much recent progress. An important recent work in this direction is that of Kachru, Kallosh, Linde and Trivedi [1], who argue that metastable de Sitter vacua with all moduli stabilized can be constructed in type IIb string theory, at least in an effective potential framework. KKLT suggested a recipe by which this could be done, following previous work of many authors on moduli stabilization by fluxes (a very incomplete list includes [28]–[39]) and especially Giddings, Kachru and Polchinski [40] who developed a class of IIb flux compactifications which stabilize the dilaton and complex structure moduli Some advantages of this construction are that it allows fixing the dilaton to weak coupling by making an appropriate choice of flux, and that cancellations can bring the flux contribution to the potential below the string scale.
