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.

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]
, 2010 The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

Correlation functions of spinor current multiplets in N $$ \mathcal{N} $$ = 1 superconformal theory
Journal of High Energy Physics, 2021 We consider N $$ \mathcal{N} $$ = 1 superconformal field theories in four dimensions possessing an additional conserved spinor current multiplet S α and study three-point functions involving such an operator.

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.

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.

A new duality between N $$ \mathcal{N} $$ = 8 superconformal field theories in three dimensions
Journal of High Energy Physics, 2018 We propose a new duality between two 3d N $$ \mathcal{N} $$ = 8 superconformal Chern-Simons-matter theories: the U(3)1 × U(3)−1 ABJM theory and a theory consisting of the product between the (SU(2)3 × SU(2)− 3)/ℤ2 BLG theory and a free N $$ \mathcal{N} $$

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 ...

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.

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 ...

Nonperturbative unification and extended supersymmetry [PDF]
Physics Letters B, 1989 Abstract We consider the nonperturbative unification scenario proposed by Maiani, Parisi and Petronzio in N =2 supersymmetric extensions of the standard model. Low-energy gauge coupling constants are computed using two-loop renormalization group equations, with a mass spectrum deduced from simple assumptions on the soft terms necessary to break ...
