Nonlinear sigma models with AdS supersymmetry in three dimensions
Daniel Butter, Sergei M. Kuzenko, Gabriele Tartaglino-Mazzucchelli
In three-dimensional anti-de Sitter (AdS) space, there exist several realizations of N-extended supersymmetry, which are traditionally labelled by two non-negative integers p>=q su…
Relating harmonic and projective descriptions of N=2 nonlinear sigma models
Daniel Butter
Recent papers have established the relationship between projective superspace and a complexified version of harmonic superspace. We extend this construction to the case of general…
The linear multiplet and ectoplasm
Daniel Butter, Sergei M. Kuzenko, Joseph Novak
In the framework of the superconformal tensor calculus for 4D N=2 supergravity, locally supersymmetric actions are often constructed using the linear multiplet. We provide a superf…
Extended supersymmetric sigma models in AdS_4 from projective superspace
Daniel Butter, Sergei M. Kuzenko, Ulf Lindstrom +1
There exist two superspace approaches to describe N=2 supersymmetric nonlinear sigma models in four-dimensional anti-de Sitter (AdS_4) space: (i) in terms of N=1 AdS chiral superfi…
Generating higher-derivative couplings in N=2 supergravity
Daniel Butter, Sergei M. Kuzenko
Using a recently developed off-shell formulation for general 4D N=2 supergravity-matter systems, we propose a construction to generate higher derivative couplings. We address here…
Component reduction in N=2 supergravity: the vector, tensor, and vector-tensor multiplets
Daniel Butter, Joseph Novak
Recent advances in curved N=2 superspace methods have rendered the component reduction of superspace actions more feasible than in the past. In this paper, we consider models invol…
