Fayet-Iliopoulos terms in supergravity and cosmology (2004)
Binetruy, P, Dvali, G, Kallosh, R
We clarify the structure of N = 1 supergravity in 1+3 dimensions with constant Fayet-Iliopoulos (FI) terms. The FI terms gxi induce non-vanishing R-charges for the fermions and the superpotential....
We study the embedding of cosmic strings, related to the Abrikosov-Nielsen-Olesen vortex solution, into d = 4, N = 1 supergravity. We find that the local cosmic string solution which saturates the...
Hypermultiplets, domain walls, and supersymmetric attractors (2001)
Ceresole, A, Dall'Agata, G, Kallosh, R
We establish general properties of supersymmetric flow equations and of the superpotential of five-dimensional N=2 gauged supergravity coupled to vector multiplets and hypermultiplets. We provide...
New formulations of D=10 supersymmetry and D8-O8 domain walls (2001)
Bergshoeff, E, Kallosh, R, Ortin, T, Roest, D
We discuss a generalized form of IIA/IIB supergravity depending on all R-R potentials C-(p) (p = 0, 1,..., 9) as the effective field theory of type IIA/IIB superstring theory. For the IIA case we...
Supersymmetry of RS bulk and brane (2001)
We review the construction of actions with supersymmetry on spaces with a domain wall. The latter objects act as sources inducing a jump in the gauge coupling constant. Despite these singularities,...

Superconformal symmetry, supergravity and cosmology (2000)
Kallosh, R, Kofman, L, Linde, A
We introduce the general N = 1 gauge theory superconformally coupled to supergravity. The theory has local SU(2, 2\1) symmetry and no dimensional parameters. The superconformal origin of the...
Gravitino production after inflation - art. no. 103503 (2000)
Kallosh, R, Kofman, L, Linde A,
We investigate the production of gravitinos in a cosmological background. Gravitinos can be produced during preheating after inflation due to a combined effect of interactions with an oscillating...
Conformal symmetry of supergravities in AdS spaces (1999)
We show that the background field method applied to supergravity in AdS space-time provides the path integral for the theory in the bulk with conformal symmetry associated with the isometry of the...
Black holes and superconformal mechanics (1998)
Kallosh, R, Kumar, J, Townsend, PK
The dynamics of a (super)particle near the horizon of an extreme Reissner-Nordstrom black hole is shown to be governed by an action that reduces to a (super)conformal mechanics model in the limit of...
Conformal theory of M2, D3, M5 and 'D1+D5' branes (1998)
Kallosh, R, Kumar, J, Townsend, PK
The bosonic actions for M2, D3 and M5 branes in their own d-dimensional near-horizon background are given in a manifestly SO(p+1,2) x SO(d-p-1) invariant form (p = 2,3,5). These symmetries result...
M 5-brane and superconformal (0,2) tensor multiplet in six dimensions (1998)
We present a gauge-fixed M 5-brane action: a 6-dimensional field theory of a self-interacting (0,2) tensor multiplet with 32 world-volume supersymmetries. The quadratic pan of this action is shown to...
Superparticle actions and gauge fixings (1992)
Recently, a covariant quantization for the superparticle has been performed. Here we show the complete gauge fixing procedure to obtain the correct BRST operator from the action proposed by one of...
