Supersymmetric D-branes on flux backgrounds
arXiv:hep-th/0701093 · doi:10.1002/prop.200610354
Abstract
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-terms associated with the N=1 four-dimensional description of space-time filling D-branes are presented. The massless spectrum of calibrated D-branes can be characterized in terms of cohomology groups of a differential complex canonically induced on the D-branes by the underlying generalized complex structure.
