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.

Poisson geometry of sigma models with extended supersymmetry [PDF]

, 2002
We consider a general N =(2,2) non-linear sigma model with a torsion. We show that the consistency of N =(2,2) supersymmetry implies that the target manifold is necessary equipped with two (in general, different) Poisson structures. Finally we argue that

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.

Superfield realization of hidden R-symmetry in extended supersymmetric gauge theories and its applications

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.

Weak gravity versus scale separation

Journal of High Energy Physics, 2022
We give evidence that fully supersymmetric Anti-de Sitter vacua of extended supergravity with a residual gauge group containing an abelian factor cannot be scale separated as a consequence of the weak gravity conjecture. We prove this for N = 2 and N = 8

Gauged (Super)Conformal Models

Physical Sciences Forum, 2023
Superconformal mechanics describes superparticle dynamics in near-horizon geometries of supersymmetric black holes. We systematically study the minimal compatible set of constraints required for a gauged superconformal symmetry.

Is chiral supersymmetry emanant or emergent?

Journal of High Energy Physics
The extended Majorana Nicolai model is one of the simplest models of supersymmetry realized on a fermionic chain in 1 + 1 dimensions. Within a certain parameter region, the extended theory breaks the supersymmetry spontaneously, but it has a ...

Pauli-Lubanski, supertwistors, and the superspinning particle

Journal of High Energy Physics, 2017
We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics.

Degrees of Metastability in Gauge Mediated Supersymmetry Breaking [PDF]

, 2011
This thesis consists of an investigation into supersymmetry and its breaking. Emphasis is placed on the question of metastability and the role of non-topological solitons in the hidden sector.

IIB black hole horizons with five-form flux and extended supersymmetry [PDF]

, 2011
We classify under some assumptions the IIB black hole horizons with 5-form flux preserving more than 2 supersymmetries. We find that the spatial horizon sections with non-vanishing flux preserving 4 supersymmetries are locally isometric either to S1 × S3
