Vacua 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 کاملNew 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 کاملThe Maximal D=4 Supergravities
All maximal supergravities in four space-time dimensions are presented. The ungauged Lagrangians can be encoded in an E7(7)\Sp(56;R)/GL(28) matrix associated with the freedom of performing electric/magnetic duality transformations. The gauging is defined in terms of an embedding tensor Θ which encodes the subgroup of E7(7) that is realized as a local invariance. This embedding tensor may imply ...
متن کاملThe Maximal D=5 Supergravities
The general Lagrangian for maximal supergravity in five spacetime dimensions is presented with vector potentials in the 27 and tensor fields in the 27 representation of E6(6). This novel tensor-vector system is subject to an intricate set of gauge transformations, describing 3(27 − t) massless helicity degrees of freedom for the vector fields and 3t massive spin degrees of freedom for the tenso...
متن کاملThe Maximal D=7 Supergravities
The general seven-dimensional maximal supergravity is presented. Its universal Lagrangian is described in terms of an embedding tensor which can be characterized group-theoretically. The theory generically combines vector, two-form and three-form tensor fields that transform into each other under an intricate set of nonabelian gauge transformations. The embedding tensor encodes the proper distr...
