(Non-)Abelian Gauged Supergravities in Nine Dimensions
E. Bergshoeff, T. de Wit, U. Gran +2
We construct five different two-parameter massive deformations of the unique nine-dimensional N=2 supergravity. All of these deformations have a higher-dimensional origin via Scher…
Superconformal N=2, D=5 matter with and without actions
Eric Bergshoeff, Sorin Cucu, Tim de Wit +4
We investigate N=2, D=5 supersymmetry and matter-coupled supergravity theories in a superconformal context. In a first stage we do not require the existence of a Lagrangian. Under…
Weyl multiplets of N=2 conformal supergravity in five Dimensions
Eric Bergshoeff, Sorin Cucu, Martijn Derix +3
We construct the Weyl multiplets of N=2 conformal supergravity in five dimensions. We show that there exist two different versions of the Weyl multiplet, which contain the same gau…
T-duality and Actions for Non-BPS D-branes
E. A. Bergshoeff, M. de Roo, T. C. de Wit +2
We employ T-duality to restrict the tachyon dependence of effective actions for non-BPS D-branes. For the Born-Infeld part the criteria of T-duality and supersymmetry are satisfied…
