Quantum extended supersymmetries

Annalen der Physik, 2004
AbstractWe analyse some quantum multiplets associated with extended supersymmetries. We study in detail the general form of the causal (anti)commutation relations. The condition of positivity of the scalar product imposes severe restrictions on the (quantum) model.

Nonlinear N = 2 $$ \mathcal{N}=2 $$ global supersymmetry

Journal of High Energy Physics, 2017
We study the partial breaking of N = 2 $$ \mathcal{N}=2 $$ global supersymmetry, using a novel formalism that allows for the off-shell nonlinear realization of the broken supersymmetry, extending previous results scattered in the literature.

Generalized Faddeev–Popov method for a deformed supersymmetric Yang–Mills theory

Physics Letters B, 2015
In this paper, we will study the deformation of a three dimensional N=2 supersymmetry gauge theory. We will deform this theory by imposing non-anticommutativity. This will break the supersymmetry of the theory from N=2 supersymmetry to N=1 supersymmetry.

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.

Internal supersymmetry and small-field Goldstini

Journal of High Energy Physics, 2018
The dynamics of the Goldstino mode of spontaneously broken supersymmetry is universal, being fully determined by the non-linearly realized symmetry. We investigate the small-field limit of this theory.

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 ...

Complete superspace classification of three-dimensional Chern-Simons-matter theories coupled to supergravity

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.

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 ...

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.
