The Gravitational Action in Asymptotically AdS and Flat Spacetimes
Per Kraus, Finn Larsen, Ruud Siebelink
The divergences of the gravitational action are analyzed for spacetimes that are asymptotically anti-de Sitter and asymptotically flat. The gravitational action is rendered finite…
The D2-D6 System and a Fibered AdS Geometry
Oskar Pelc, Ruud Siebelink
The system of D2 branes localized on or near D6 branes is considered. The world-volume theory on the D2 branes is investigated, using its conjectured relation to the near-horizon g…
Vector-tensor multiplets
P. Claus, B. de Wit, M. Faux +3
We review the coupling of N=2 supergravity to vector-tensor multiplets, based on the method of superconformal multiplet calculus.
The low-energy effective action for perturbative heterotic strings on and the d=4 N=2 vector-tensor multiplet
R. Siebelink
We consider d=4 N=2 supergravity theories which serve as low-energy effective actions for heterotic strings on K_3 \times T^2. At the perturbative level we construct a new version…
The Vector-Tensor Supermultiplet with Gauged Central Charge
P. Claus, B. de Wit, M. Faux +3
The vector-tensor multiplet is coupled off-shell to an N=2 vector multiplet such that its central charge transformations are realized locally. A gauged central charge is a necessar…
Hiding Anomalies
F. De Jonghe, R. Siebelink, W. Troost
Anomalies can be anticipated at the classical level without changing the classical cohomology, by introducing extra degrees of freedom. In the process, the anomaly does not quite d…
