We derive the lagrangian and the transformation laws of N = 4 gauged supergravity coupled to matter multiplets whose σ-model of the scalars is SU(1,1)/U(1)⊗SO(6,6+n)/SO(6)⊗SO(6+n) and which corresponds to the effective lagrangian of the type-IIB string compactified on the T6/2 orientifold with fluxes turned on and in presence of n D3-branes. The gauge group is T12⊗G where G is the gauge group on the brane and T12 is the gauge group on the bulk corresponding to the gauged translations of the R-R…

New D = 4 gauged supergravities from N=4 orientifolds with fluxes

We consider classes of T 6 -orientifolds, where the orientifold projection contains an inversion I 9?p on 9?p coordinates, transverse to a Dp-brane. In absence of fluxes, the massless sector of these

Gauged N=1 supergravity and the embedding tensor formalism

English. We report about our research on gauged supergravities with particular applications in four-dimensional N = 1 theories. Part of this work was presented already in [1–3]. In the course of the
