The map between conformal hypercomplex/hyper-Kaehler and quaternionic(-Kaehler) geometry

Eric Bergshoeff, Sorin Cucu, Tim de Wit +3

We review the general properties of target spaces of hypermultiplets, which are quaternionic-like manifolds, and discuss the relations between these manifolds and their symmetry ge…

Rotating Solutions of Non-relativistic String Theory

Joaquim Gomis, Filippo Passerini

We construct classical rotating solutions of Non-relativistic String Theory. The relation among the energy and angular momenta for these solutions is of the type E=J^2. Some of the…

On the fakeness of fake supergravity

Alessio Celi, Anna Ceresole, Gianguido Dall'Agata +2

We revisit and complete the study of curved BPS-domain walls in matter-coupled 5D, N=2 supergravity and carefully analyse the relation to gravitational theories known as "fake supe…

Supergravity with Fayet-Iliopoulos terms and R-symmetry

Antoine Van Proeyen

The simplest examples of gauged supergravities are N=1 or N=2 theories with Fayet-Iliopoulos (FI) terms. FI terms in supergravity imply that the R-symmetry is gauged. Also the U(1)…

Revisiting the Fradkin-Vilkovisky Theorem

J. Govaerts, F. G. Scholtz

The status of the usual statement of the Fradkin-Vilkovisky theorem, claiming complete independence of the Batalin-Fradkin-Vilkovisky path integral on the gauge fixing "fermion" ev…

Giant Gravitons in AdS_3 x S^3 x T^4 as Fuzzy Cylinders

Bert Janssen, Yolanda Lozano, Diego Rodriguez-Gomez

Using the non-Abelian action for coincident Type IIB gravitational waves proposed in hep-th/0303183 we show that giant gravitons in the AdS_3 x S^3 x T^4 background can be describe…

Hypermultiplets and hypercomplex geometry from 6 to 3 dimensions

Jan Rosseel, Antoine Van Proeyen

The formulation of hypermultiplets that has been developed for 5-dimensional matter multiplets is by dimensional reductions translated into the appropriate spinor language for 6 an…

Getting just the Supersymmetric Standard Model at Intersecting Branes on the Z6-orientifold

Gabriele Honecker, Tassilo Ott

In this paper, globally N=1 supersymmetric configurations of intersecting D6-branes on the Z6-orientifold are discussed, involving also fractional branes. It turns out rather mirac…

Chiral Supersymmetric Standard Model Spectra from Orientifolds of Gepner Models

T. P. T. Dijkstra, L. R. Huiszoon, A. N. Schellekens

We construct d=4,N=1 orientifolds of Gepner models with just the chiral spectrum of the standard model. We consider all simple current modular invariants of c=9 tensor products of…

N=2 supergravity in five dimensions revisited

Eric Bergshoeff, Sorin Cucu, Tim de Wit +3

We construct matter-coupled N=2 supergravity in five dimensions, using the superconformal approach. For the matter sector we take an arbitrary number of vector-, tensor- and hyper-…

Fayet-Iliopoulos Terms in Supergravity and Cosmology

Pierre Binetruy, Gia Dvali, Renata Kallosh +1

We clarify the structure of N=1 supergravity in 1+3 dimensions with constant FI terms. The FI terms induce non-vanishing R-charges for the fermions and the superpotential. Therefor…

D-term strings

Gia Dvali, Renata Kallosh, Antoine Van Proeyen

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 s…
