Kähler moduli inflation on large volume moduli stabilization
In this paper we present a two-field inflation model, which distinguishes itself with a non-canonical kinetic lagrangian and comes from the large volume approach to the moduli stabilization in flux compactification of type IIB superstring on a Calabi-Yau orientifold of h(1,2) > h(1,1) ≥ 4. The Kähler moduli are classified as volume modulus, heavy moduli and two light moduli. The axion-dilaton, ...

متن کاملModuli and Kähler potential in fermionic strings.
We study the problem of identifying the moduli fields in fermionic four-dimensional string models. We deform a free-fermionic model by introducing exactly marginal operators in the form of Abelian Thirring interactions on the world-sheet, and show that their couplings correspond to the untwisted moduli fields. We study the consequences of this method for simple free-fermionic models which corre...
متن کاملD-Moduli Stabilization
The matter sector of four-dimensional effective supergravity models obtained from the weakly coupled heterotic string contains many moduli. In particular, flat directions of the D-term part of the scalar potential in the presence of an anomalous U(1) give rise to massless chiral multiplets which have been referred to elsewhere as Dmoduli. The stabilization of these moduli is necessary for the d...
متن کاملModuli Stabilization from Fluxes
Compactifications of IIB string theory with internal NS and RR three-form flux are computationally attractive in that the lifting of moduli is via a perturbative and often explicitly calculable (super)potential. We focus on the T /Z2 orientifold, and provide an illustative N = 2 example. For other choices of flux, the resulting equations of motion can be solved to yield N = 0, 1, 2 or 3 supersy...
