The superfield quantisation of a superparticle action with an extended line element [PDF]
, 2005 A massive superparticle action based on the generalised line element in N = 1 global superspace is quantised canonically. A previous method of quantising this action, based on a Fock space analysis, showed that states existed in three supersymmetric ...

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 $$ \mathcal{N} $$

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.

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.

Split extended supersymmetry from intersecting branes [PDF]
, 2006 We study string realizations of split extended supersymmetry, recently proposed in hep-ph/0507192. Supersymmetry is broken by small ($\epsilon $) deformations of intersection angles of $D$-branes giving tree-level masses of order $m_0^2\sim \epsilon M_s ...

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.

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.

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 ...

Constraints on chiral operators in N=2 SCFTs [PDF]
, 2014 : We study certain higher-spin chiral operators in (formula presented)(formula presented) superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized Argyres-Seiberg-Gaiotto duality (“type A”

Non-uniqueness of the supersymmetric extension of the O(3) σ-model
Journal of High Energy Physics, 2017 We study the supersymmetric extensions of the O(3) σ-model in 1+1 and 2+1 dimensions. We show that it is possible to construct non-equivalent supersymmetric versions of a given model sharing the same bosonic sector and free from higher-derivative terms.
