Type 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...

Standard-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...

Flux vacua in DBI type Einstein-Maxwell theory

We study compactification of extra dimensions in a theory of Dirac-Born-Infeld (DBI) type gravity. We investigate the solution for Minkowski spacetime with an S2 extra space as well as that for de Sitter spacetime (S4) with an S2 extra space. They are derived by the effective potential method in the presence of the magnetic flux on the extra sphere. We also consider the higher dimensional gener...

Flux-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...

Anomalous U(1)’s in Type I and Type IIB D=4, N=1 string vacua

We study the cancellation of U (1) anomalies in Type I and Type IIB D = 4, N = 1 string vacua. We first consider the case of compact toroidal Z N Type IIB orientifolds and then proceed to the non-compact case of Type IIB D3 branes at orbifold and orientifold singularities. Unlike the case of the heterotic string we find that for each given vacuum one has generically more than one U (1) with non...
