New Gauged N=8, D=4 Supergravities
New gaugings of four dimensional N = 8 supergravity are constructed, including one which has a Minkowski space vacuum that preserves N = 2 supersymme-try and in which the gauge group is broken to SU(3) × U(1) 2. Previous gaugings used the form of the ungauged action which is invariant under a rigid SL(8, R) symmetry and promoted a 28-dimensional subgroup (SO(8), SO(p, 8 − p) or the non-semi-sim...
متن کاملGauged N=4 Supergravities
We present the complete gauged N = 4 (half-maximal) supergravities in four and five spacetime dimensions coupled to an arbitrary number of vector mul-tiplets. The gaugings are parameterized by a set of appropriately constrained constant tensors, which transform covariantly under the global symmetry groups SL(2) × SO(6, n) and SO(1, 1) × SO(5, n), respectively. In terms of these tensors the univ...
متن کاملNew D = 4 gauged supergravities from N = 4 orientifolds with fluxes
We consider classes of T6–orientifolds, where the orientifold projection contains an inversion I9−p on 9 − p coordinates, transverse to a Dp–brane. In absence of fluxes, the massless sector of these models corresponds to diverse forms of N = 4 supergravity, with six bulk vector multiplets coupled to N = 4 Yang–Mills theory on the branes. They all differ in the choice of the duality symmetry cor...
متن کاملVacua of Maximal Gauged D = 3 Supergravities
We analyze the scalar potentials of maximal gauged three-dimensional supergravities which reveal a surprisingly rich structure. In contrast to maximal supergravities in dimensions D ≥ 4, all these theories admit a maximally supersymmetric (N = 16) ground state with negative cosmological constant Λ < 0, except for the gauge group SO(4, 4)2, for which Λ = 0. We compute the mass spectra of bosonic...
متن کاملSupersymmetry of Black Strings in D = 5 Gauged Supergravities
Supersymmetry of five dimensional string solutions is examined in the context of gauged D = 5, N = 2 supergravity coupled to abelian vector multiplets. We find magnetic black strings preserving one quarter of supersymmetry and approaching the half-supersymmetric product space AdS3 × H near the event horizon. The solutions thus exhibit the phenomenon of supersymmetry enhancement near the horizon...
