Algebras and non-geometric flux vacua
In this work we classify the subalgebras satisfied by non-geometric Q-fluxes in type IIB orientifolds on T/(Z2 × Z2) with three moduli (S, T, U). We find that there are five subalgebras compatible with the symmetries, each one leading to a characteristic flux-induced superpotential. Working in the 4-dimensional effective supergravity we obtain families of supersymmetric AdS4 vacua with all modu...
متن کاملFiniteness of Flux Vacua from Geometric Transitions
We argue for finiteness of flux vacua around type IIB CY singularities by computing their gauge theory duals. This leads us to propose a geometric transition where the compact 3-cycles support both RR and NS flux, while the open string side contains 5-brane bound states. By a suitable combination of S duality and symplectic transformations, both sides are shown to have the same IR physics. The ...
متن کاملFlux Vacua and Supermanifolds
As been recently pointed out, physically relevant models derived from string theory require the presence of non-vanishing form fluxes besides the usual geometrical constraints. In the case of NS-NS fluxes, the Generalized Complex Geometry encodes these informations in a beautiful geometrical structure. On the other hand, the R-R fluxes call for supergeometry as the underlying mathematical frame...
متن کاملBuilding MSSM Flux Vacua
We construct N = 1 and N = 0 chiral four-dimensional vacua of flux compactification in Type IIB string theory. These vacua have the common features that they are free of tadpole instabilities (both NSNS and RR) even for models with N = 0 supersymmetry. In addition, the dilaton/complex structure moduli are stabilised and the supergravity background metric is warped. We present an example in whic...
متن کاملGeneralized Flux Vacua
We consider type II string theory compactified on a symmetric T /Z2 orientifold. We study a general class of discrete deformations of the resulting fourdimensional supergravity theory, including gaugings arising from geometric and “nongeometric” fluxes, as well as the usual R-R and NS-NS fluxes. Solving the equations of motion associated with the resulting N = 1 superpotential, we find parametr...
