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.

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 ...

Extended supersymmetry and the vacuum
Physics Letters B, 1983 Abstract Using light-cone superspace techniques and the adiabatic formalism, we show that the level shift between the bare and the physical vacua is zero order by order in perturbation theory in theories exhibiting extended supersymmetry.

Vacua analysis in extended supersymmetry compactifications [PDF]
Fortschritte der Physik, 2012 AbstractWe analyse geometric type IIA flux compactifications leading to 𝒩 = 4 gauged supergravities in four dimensions. The complete landscape of isotropic vacua is presented, which turns out to belong to a unique theory. The solutions admit an uplift to maximal supergravity due to the vanishing of the flux‐induced tadpoles for all the supersymmetry ...

Partial N $$ \mathcal{N} $$ = 2 supersymmetry breaking and deformed hypermultiplets
Journal of High Energy Physics, 2019 We study partial supersymmetry breaking from N $$ \mathcal{N} $$ = 2 to N $$ \mathcal{N} $$ = 1 by adding non-linear terms to the N $$ \mathcal{N} $$ = 2 supersymmetry transformations.

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 ...

Supersymmetric many-body Euler–Calogero–Moser model
Physics Letters B, 2019 We explicitly construct a supersymmetric so(n) spin-Calogero model with an arbitrary even number N of supersymmetries. It features 12Nn(n+1) rather than Nn fermionic coordinates and a very simple structure of the supercharges and the Hamiltonian.

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 ...

Linearised actions for N $$ \mathcal{N} $$ -extended (higher-spin) superconformal gravity
Journal of High Energy Physics, 2019 The off-shell actions for N $$ \mathcal{N} $$ -extended conformal supergravity theories in three dimensions were formulated in [1, 2] for 1 ≤ N $$ \mathcal{N} $$ ≤ 6 using a universal approach.
