We investigate whether a class of models describing F-theory compactifications admits a specific type of flux vacua with an exponentially small vacuum expectation value of the superpotential, by generalizing a method recently developed in type IIB flux compactifications. First we clarify that a restricted choice of ${G}_{4}$-flux components reduces a general flux superpotential into a simple form, which promotes the existence of supersymmetric vacua with one flat direction at the perturbative level. Then we utilize the techniques of mirror symmetry to determine one-instanton corrections to the potential and investigate in detail the vacuum solutions of a particular model.read more

F-theory flux vacua at large complex structure
TL;DR: In this article, the flux-induced F-term potential in 4D F-theory compactifications at large complex structure is analyzed. But the analysis is restricted to type IIB orientifolds, where both families of vacua are present.

Moduli stabilization in asymptotic flux compactifications
TL;DR: In this paper , the moduli dependence of the vacuum conditions is shown to be polynomial with a dependence given by sl(2)-weights of the fluxes, which can be extracted in any asymptotic regime, even when essential exponential corrections have to be present for consistency.

Counting flux vacua
TL;DR: In this article, a technique for computing expected numbers of vacua in gaussian ensembles of supergravity theories was developed, and applied to derive an asymptotic formula for the index counting all flux supersymmetric vacua with signs in Calabi-Yau compactification of type b string theory, which becomes exact in the limit of a large number of fluxes.

Constraints on low-dimensional string compactifications
TL;DR: In this article, the authors studied the restrictions imposed by cancellation of the tadpoles for two-, three-, and four-form gauge fields in string theory, and explored the relation of the membranes and three-branes to the nonperturbative space-time superpotential.

On Calabi-Yau Complete Intersections in Toric Varieties
Victor V. Batyrev,Lev A. Borisov +1 more
TL;DR: In this article, it was shown that the combinatorial duality proposed by second author agrees with the duality for Hodge numbers predicted by mirror symmetry, and that the complete verification of mirror symmetry predictions for singular Calabi-Yau varieties of arbitrary dimension requires considerations of string-theoretic Hodge number.
