چکیده
Abstract We derive the 3D N = 1 superpotential for closed string sector of type IIB supergravity on toroidal O5 orientifolds with co-calibrated G2 structure and RR background flux. find that such compactifications can provide full moduli stabilization supersymmetric $$\hbox {AdS}_3$$ AdS 3 vacua, once we include brane-supersymmetry-breaking also indication existence classical de Sitter solutions. The latter however are rather difficult to reconcile “shape” flux quantization. discuss possibility achieving scale separation in {dS}_3$$ dS but effects seem be hindered by geometric

On supersymmetric Minkowski vacua in IIB orientifolds
Supersymmetric Minkowski vacua in IIB orientifold compactifications based on orbifolds with background fluxes and non-perturbative superpotentials are investigated. Especially, microscopic requirements and difficulties to obtain such vacua are discussed. We show that orbifold models with one and two complex structure moduli and supersymmetric 2-form flux can be successfully stabilized to such v...
متن کاملType IIB Flux Vacua at Large Complex Structure
ly in terms of flux-modulus variables alone, with no dependence on Yukawa couplings; and (2) for any particular Calabi-Yau, we can actually produce a vacuum corresponding to any abstract (X,Yî, Zâ) ∈ Xn at any chosen values of moduli (τ, ta) by simply tuning the internal fluxes. As seen from the decomposition of the mass matrix M2 τ,C in (2.23), an added benefit of covariantly constant Yukawa c...
متن کاملStandard-like Models as Type IIB Flux Vacua
We construct new semi-realistic Type IIB flux vacua on Z2 × Z2 orientifolds with threeand fourStandard Model (SM) families and up to three units of quantized flux. The open-string sector is comprised of magnetized D-branes and is T-dual to supersymmetric intersecting D6brane constructions. The SM sector contains magnetized D9-branes with negative D3-brane charge contribution. There are large cl...
متن کاملFlux-vacua in Two Dimensional String Theory
We analyze the two dimensional type 0 theory with background RR-fluxes. Both the 0A and the 0B theory have two distinct fluxes q and q̃. We study these two theories at finite temperature (compactified on a Euclidean circle of radius R) as a function of the fluxes, the tachyon condensate μ and the radius R. Surprisingly, the dependence on q, q̃ and μ is rather simple. The partition function is the...
متن کاملPerturbative Vacua from IIB Matrix Model
It has not been clarified whether a matrix model can describe various vacua of string theory. In this paper, we show that the IIB matrix model includes type IIA string theory. In the naive large N limit of the IIB matrix model, configurations consisting of simultaneously diagonalizable matrices form a moduli space, although the unique vacuum would be determined by complicated dynamics. This mod...
