Component decompositions and adynkra libraries for supermultiplets in lower dimensional superspaces
Journal of High Energy Physics, 2021 We present Adynkra Libraries that can be used to explore the embedding of multiplets of component field (whether on-shell or partial on-shell) within Salam-Strathdee superfields for theories in dimension nine through four.

Symmetries of supergravity backgrounds and supersymmetric field theory
Journal of High Energy Physics, 2020 In four spacetime dimensions, all N $$ \mathcal{N} $$ = 1 supergravity-matter systems can be formulated in the so-called U(1) superspace proposed by Howe in 1981.

AdS (super)projectors in three dimensions and partial masslessness
Journal of High Energy Physics, 2021 We derive the transverse projection operators for fields with arbitrary integer and half-integer spin on three-dimensional anti-de Sitter space, AdS3. The projectors are constructed in terms of the quadratic Casimir operators of the isometry group SO(2 ...

New duality-invariant models for nonlinear supersymmetric electrodynamics
Journal of High Energy Physics, 2023 We propose a new family of U(1) duality-invariant models for nonlinear N $$ \mathcal{N} $$ = 1 supersymmetric electrodynamics coupled to supergravity.

Generating Geodesic Flows and Supergravity Solutions [PDF]
, 2009 We consider the geodesic motion on the symmetric moduli spaces that arise after timelike and spacellike reductions of supergravity theories. The geodesics correspond to timelike respectively spacelike p-brane Solutions when they are lifted over a p ...

Fine-tuning constraints on supergravity models [PDF]
Physics Letters B, 2000 We discuss fine-tuning constraints on supergravity models. The tightest constraints come from the experimental mass limits on two key particles: the lightest CP even Higgs boson and the gluino. We also include the lightest chargino which is relevant when universal gaugino masses are assumed. For each of these particles we show how fine-tuning increases
