de Sitter String Vacua from Perturbative Kähler Corrections and Consistent D - terms
نویسنده
چکیده
We present a new way to construct de Sitter vacua in type IIB flux compactifications, in which moduli stabilization and D-term uplifting can be combined in a manner consistent with the supergravity constraints. Here, the closed string fluxes fix the dilaton and the complex structure moduli while perturbative quantum corrections to the Kähler potential stabilize the volume Kähler modulus in an AdS4-vacuum. Then, the presence of magnetized D7-branes in this setup provides supersymmetric D-terms in a fully consistent way which uplift the AdS4-vacuum to a metastable dS-minimum.

de Sitter String Vacua from Kähler Uplifting
We present a new way to construct de Sitter vacua in type IIB flux compactifications, in which the interplay of the leading perturbative and non-perturbative effects stabilize all moduli in dS vacua at parametrically large volume. Here, the closed string fluxes fix the dilaton and the complex structure moduli while the universal leading perturbative quantum correction to the Kähler potential to...
متن کاملModuli Stabilization in Meta-Stable Heterotic Supergravity Vacua
We revisit the issue of moduli stabilization in a class of N = 1 four dimensional supergravity theories which are low energy descriptions of standard perturbative heterotic string vacua compactified on Calabi–Yau spaces. In particular, we show how it is possible to stabilize the universal dilaton and Kähler moduli in a de Sitter/Minkowski vacuum with low energy supersymmetry breaking by means o...
متن کاملDe Sitter Vacua from Matter Superpotentials
Consistent uplifting of AdS vacua in string theory often requires extra light degrees of freedom in addition to those of a (Kähler) modulus. Here we consider the possibility that de Sitter and Minkowski vacua arise due to hidden sector matter interactions. We find that, in this scheme, the hierarchically small supersymmetry breaking scale can be explained by the scale of gaugino condensation an...
متن کاملStringy corrections to Kähler potentials, SUSY breaking, and the cosmological constant problem
The moduli of N = 1 compactifications of IIB string theory can be stabilized by a combination of fluxes (which freeze complex structure moduli and the dilaton) and nonperturbative superpotentials (which freeze Kähler moduli), typically leading to supersymmetric AdS vacua. We show that stringy corrections to the Kähler potential qualitatively alter the structure of the effective scalar potential...
متن کاملA New Handle on de Sitter Compactifications
We construct a large new class of de Sitter (and anti de Sitter) vacua of critical string theory from flux compactifications on products of Riemann surfaces. In the construction, the leading effects stabilizing the moduli are perturbative. We show that these effects self-consistently dominate over standard estimates for further α and quantum corrections, via tuning available from large flux and...
