4D N $$ \mathcal{N} $$ = 1 Kaluza-Klein superspace
Journal of High Energy Physics, 2020 Motivated by recent efforts to encode 11D supergravity in 4D N $$ \mathcal{N} $$ = 1 superfields, we introduce a general covariant framework relevant for describing any higher dimensional supergravity theory in external 4D N $$ \mathcal{N} $$ = 1 ...

Journal of High Energy Physics, 2018 For extended N $$ \mathcal{N} $$ ≤ 8 supersymmetry we classify all possible gauge groups for a scalar multiplet allowed by the algebras of global and local supersymmetry in three dimensions. A detailed discussion of supersymmetry enhancement is included.

Vacua of ω-deformed SO(8) supergravity
Journal of High Energy Physics, 2022 We perform a detailed analysis of the vacua of ω-deformed SO(8) supergravity in four dimensions. In particular, using Tensorflow-based numerical methods, we track how the equilibria of the theory change when varying the electric-magnetic deformation ...

Superspace higher derivative terms in two dimensions
Journal of High Energy Physics, 2017 We study (2, 2) and (4, 4) supersymmetric theories with superspace higher derivatives in two dimensions. A characteristic feature of these models is that they have several different vacua, some of which break supersymmetry.

Superconformal duality-invariant models and N $$ \mathcal{N} $$ = 4 SYM effective action
Journal of High Energy Physics, 2021 We present N $$ \mathcal{N} $$ = 2 superconformal U(1) duality-invariant models for an Abelian vector multiplet coupled to conformal supergravity. In a Minkowski background, such a nonlinear theory is expected to describe (the planar part of) the low ...

Topologically massive gravity with extended supersymmetry [PDF]
Physical Review D, 2016 We describe the construction of $2+1$-dimensional toplogically massive adS gravity with ${\mathcal{N}}$-extended supersymmetry in superspace by means of introducing a compensating hypermultiplet for the super-Weyl invariance. For $\mathcal{N}\geq 3$ the scalar multiplet must be on shell and the potential for the scalar compensator is completely ...

Journal of High Energy Physics, 2020 We present the explicit superfield realizations of the hidden SU(4) and O(5) R-symmetries in 4D, N $$ \mathcal{N} $$ = 4 and 5D, N $$ \mathcal{N} $$ = 2 supersymmetric Yang-Mills theories in the harmonic superspace approach.

Embedding formalism for (p, q) AdS superspaces in three dimensions
Journal of High Energy Physics, 2023 We develop an embedding formalism for (p, q) anti-de Sitter (AdS) superspaces in three dimensions by using a modified version of their supertwistor description given in the literature. A coset construction for these superspaces is worked out.
