The firstclass of effects, Euclidean D3 branes which lift in M-theory to M5 branes wrapping divisorsof arithmetic genus 1 in the fourfold, is relatively well understood. The… 

Magnetized E3-brane instantons in F-theory

A bstractWe discuss E3-brane instantons in N = 1 F-theory compactifications to four dimensions and clarify the structure of E3-E3 zero modes for general world-volume fluxes. We consistently

D3 instantons in Calabi–Yau orientifolds with(out) fluxes

We investigate the instanton effects due to D3 branes wrapping a four-cycle in a Calabi–Yau orientifold with D7 branes. We study the condition for the nonzero superpotentials from the D3 instantons.

On the explicit construction and statistics of Calabi-Yau flux vacua

We explicitly construct and study the statistics of flux vacua for type IIB string theory on an orientifold of the Calabi-Yau hypersurface P[1,1,2,2,6], parametrised by two relevant complex structure

Large-volume flux compactifications: Moduli spectrum and D3/D7 soft supersymmetry breaking

We present an explicit calculation of the spectrum of a general class of string models, corresponding to Calabi-Yau flux compactifications with h1,2 > h1,1 > 1 with leading perturbative and

Brane instantons and fluxes in F-theory

A bstractWe study the combined effect of world-volume and background fluxes on Euclidean D3-brane instantons in F-theory compactifications. We derive an appropriate form of the fermionic effective

Abelian gauge symmetries and fluxed instantons in compactifications of type IIB and F-theory

We discuss the role of Abelian gauge symmetries in type IIB orientifold compactifications and their F-theory uplift. Particular emphasis is placed on U(1)s which become massive through the geometric

Stabilizing all Kähler moduli in type IIB orientifolds

We describe a simple and robust mechanism that stabilizes all Kähler moduli in Type IIB orientifold compactifications. This is shown to be possible with just one non-perturbative contribution to the



Moduli potentials in string compactifications with fluxes: Mapping the discretuum

We find de Sitter and flat space solutions with all moduli stabilized in four dimensional supergravity theories derived from the heterotic and type II string theories, and explain how all the

Compactification with Flux on K3 and Tori

We study compactifications of type-IIB string theory on a K3 × T2/Z2 orientifold in the presence of RR and NS flux. We find the most general supersymmetry preserving, Poincare invariant, vacua in

M theory, orientifolds and G - flux

We study the properties of M and F theory compactifications to three and four dimensions with background fluxes. We provide a simple construction of supersymmetric vacua, including some with

Brane/Flux Annihilation and the String Dual of a Non-Supersymmetric Field Theory

We consider the dynamics of p anti-D3 branes inside the Klebanov-Strassler geometry, the deformed conifold with M units of RR 3-form flux around the S3. We find that for p << M the system relaxes to

Flux-induced SUSY-breaking soft terms

Hierarchies from fluxes in string compactifications

Warped compactifications with significant warping provide one of the few known mechanisms for naturally generating large hierarchies of physical scales. We demonstrate that this mechanism is

De Sitter vacua in string theory

We outline the construction of metastable de Sitter vacua of type IIB string theory. Our starting point is highly warped IIB compactifications with nontrivial NS and RR three-form fluxes. By
