Hierarchies from fluxes in string compactifications
TL;DR: In this article, the authors show that the hierarchy of scales can be fixed by a choice of Ramond-Ramond and Neveu-Schwarz fluxes in the compact manifold, and give examples involving orientifold compactifications of type IIB string theory and F-theory compactifications on Calabi-Yau fourfolds.
Journal ArticleDOI
Five-dimensional supersymmetric gauge theories and degenerations of Calabi-Yau spaces
TL;DR: In this article, the authors discuss necessary conditions for existence of non-trivial renormalization group fixed points and find all possible gauge groups and matter content which satisfy them, and explore connections between aspects of the gauge theory and Calabi-Yau geometry.
Journal ArticleDOI
Vector Bundles and F Theory
TL;DR: In this paper, the construction of holomorphic G bundles over elliptic Calabi-Yau manifolds, for various groups G, has been studied, and several detailed comparisons between the heterotic string and F theory are made.

Model building with $F$-theory
Ron Donagi,Martijn Wijnholt +1 more
TL;DR: In this article, the authors extend the class of models by considering $F$-theory compactifications, which may incorporate unification more naturally, and derive the charged chiral spectrum and Yukawa couplings in $N = 1$ compactifications of $F $theory with $G$-flux.
Journal ArticleDOI
GUTs and exceptional branes in F-theory — II. Experimental predictions
TL;DR: In this article, the authors consider realizations of GUT models in F-theory and show that the dynamics of the GUT model can in principle decouple from Planck scale physics, leading to a surprisingly predictive framework.

String theory dynamics in various dimensions
TL;DR: The strong coupling dynamics of string theories in dimension d ⩾ 4 are studied in this paper, where it is argued that eleven-dimensional supergravity arises as a low energy limit of the ten-dimensional Type IIA superstring.
Journal ArticleDOI
Unity of superstring dualities
Chris Hull,Paul K. Townsend +1 more
TL;DR: In this article, it was shown that the effective action for type II string theory compactified on a six-torus is N = 8 supergravity, which is known to have an E7 duality symmetry.
Journal ArticleDOI
Evidence for F-theory
TL;DR: In this paper, the authors constructed compact examples of D-manifolds for type IIB strings and showed that the construction has a natural interpretation in terms of compactification of a 12-dimensional ''F-theory''.
Journal Article
Dual polyhedra and mirror symmetry for Calabi-Yau hypersurfaces in toric varieties
TL;DR: In this article, it was shown that there exists an isomorphism between two conformal field theories corresponding to Calabi-Yau varieties from two families of algebraic compactifications of affine hypersurfaces.

D-branes, quivers, and ALE instantons
TL;DR: In this paper, the authors constructed effective field theories in type I and II superstring theories for D-branes located at points in the orbifold C~2/Z_n, whose field content is conveniently summarized by a ''quiver diagram'' and whose Lagrangian includes non-metric couplings to the moduli.
