Supersymmetric D - branes and calibrations on general N = 1 backgrounds
We study the conditions to have supersymmetric D-branes on general N = 1 backgrounds with Ramond-Ramond fluxes. These conditions can be written in terms of the two pure spinors associated to the SU(3) × SU(3) structure on TM ⊕ T ⋆ M , and can be split into two parts each involving a different pure spinor. The first involves the integrable pure spinor and requires the D-brane to wrap a generalis...
متن کاملD-Branes in Nongeometric Backgrounds
“T-fold” backgrounds are generically-nongeometric compactifications of string theory, described by T fibrations over a base N with transition functions in the perturbative T-duality group. We review Hull’s doubled torus formalism, which geometrizes these backgrounds, and use the formalism to constrain the D-brane spectrum (to leading order in gs and α ) on T fibrations over S with O(n, n;Z) mon...
متن کاملSupersymmetric D-branes on flux backgrounds
Several aspects concerning the physics of D-branes in Type II flux compactifications preserving minimal N = 1 supersymmetry in four dimensions are considered. It is shown how these vacua are completely characterized in terms of properly defined generalized calibrations for D-branes and the relation with Generalized Complex Geometry is discussed. General expressions for superpotentials and D-ter...
متن کاملComments on D-branes in flux backgrounds
We construct supergravity solutions for D-branes in nontrivial flux backgrounds. We revisit the issue of charge quantization in this framework, and show that in these backgrounds, charge need not be quantized. We also show in a particular example that the semiclassical description of branes produces integral charges. e-mail address: [email protected]
