New duality-invariant models for nonlinear supersymmetric electrodynamics

We propose a new family of U(1) duality-invariant models for nonlinear N = 1 supersymmetric electrodynamics coupled to supergravity. It includes the Cribiori-FarakosTournoy-van Proeyen supergravity-matter theory for spontaneously broken local supersymmetry with a novel Fayet-Iliopoulos term without gauged R-symmetry. We present superconformal duality-invariant models, as well as new U(1) duality-invariant models for spontaneously broken local supersymmetry.

Automated summary

In this study, a new family of U(1) duality-invariant models is proposed for the coupling between nonlinear N = 1 supersymmetric electrodynamics and supergravity. This family includes the Cribiori-FarakosTournoy-van Proeyen supergravity-matter theory for spontaneously broken local supersymmetry and introduces a novel Fayet-Iliopoulos term without gauged R-symmetry.
