Abstract: We construct a new class of non-supersymmetric ten-dimensional type II flux vacua, by studying first order differential equations which are deformations of the N=1 supersymmetry conditions. We do so within the context of Generalised Complex Geometry, where there is a natural interpretation of the N = 1 supersymmetry conditions in terms of calibration conditions for probe D-branes, called D-string, domain-wall or space-filling branes, depending on them wrapping 2, 3 or 4 non-compact dimensions. We focus on a subclass of non-supersymmetric vacua violating the D-string calibration condition, where the deformation of the calibration condition is dictated by the foliated geometry of the internal space. We present the explicit construction of an example SU(3) background.
