On Global Symmetries and Fayet-Iliopoulos Terms
Fotis Farakos, Alex Kehagias, Nikolaos Liatsos
We revisit the genuine Fayet-Iliopoulos terms of 4D N=1 supergravity. Such terms are commonly believed to preserve a global symmetry, and therefore they are in conflict with the pr…
Complex Linear Multiplets and Local Supersymmetry Breaking
Fotis Farakos, Alex Kehagias, Nikolaos Liatsos
We study supersymmetry breaking from a complex linear superfield coupled to 4D N=1 supergravity. The theory has two classically decoupled vacua, one supersymmetric and one with bro…
Weak gravity versus de Sitter
N. Cribiori, G. Dall'Agata, F. Farakos
We show that one can uncover a Dine-Seiberg problem for de Sitter critical points in supergravity theories by utilizing the magnetic weak gravity conjecture. We present a large var…
Minimal Constrained Supergravity
N. Cribiori, G. Dall'Agata, F. Farakos +1
We describe minimal supergravity models where supersymmetry is non-linearly realized via constrained superfields. We show that the resulting actions differ from the so called "de S…
Interactions of N Goldstini in Superspace
N. Cribiori, G. Dall'Agata, F. Farakos
We study field theories with N extended non-linearly realized supersymmetries, describing the couplings of models that contain N goldstini. We review all the known formulations of…
Linearized Non-Minimal Higher Curvature Supergravity
Fotis Farakos, Alex Kehagias, Konstantinos Koutrolikos
In the framework of linearized non-minimal supergravity (20/20), we present the embedding of the model and we analyze its field spectrum. As usual, the auxiliary fields o…
