Abstract We discuss supersymmetry breaking via 3-form fluxes in chiral supersymmetric type IIB orientifold vacua with D3- and D7-branes. After a general discussion of possible choices of fluxes allowing for stabilizing of a part of the moduli, we determine the resulting effective action including all soft supersymmetry breaking terms. We also extend the computation of our previous work [ hep-th/0404134 ] concerning the matter field metrics arising from various open string sectors, in particular focusing on the 1 / 2 BPS D3/D7-brane configuration. Afterwards, the F-theory lift of our constructions is investigated.
