Higgs alignment from extended supersymmetry [PDF]
We consider the effective type-II two-Higgs doublet model originating from Dirac gaugino models with extended supersymmetry in the gauge sector, which is automatically aligned in the simplest realisations.

Splitting Extended Supersymmetry [PDF]
We show how splitting supersymmetry reconciles a class of intersecting brane models with unification. The gauge sector in these models arises in multiplets of extended supersymmetry while matter states are in N=1 representations.

Yano F structures and extended supersymmetry
It is shown how extended supersymmetry realised directly on the (2, 2) semichiral superfields of a symplectic sigma model gives rise to a geometry on the doubled tangent bundle consisting of two Yano F structures on an almost para-hermitian manifold ...

Worldsheets with Extended Supersymmetry [PDF]
We determine the equations which govern the gauge symmetries of worldsheets with local supersymmetry of arbitrary rank $(N,N')$, and their possible anomalies.

Internal supersymmetry and small-field Goldstini [PDF]
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.

Doubled space and extended supersymmetry
The doubled formulation of the worldsheet provides a description of string theory in which T-duality is promoted to a manifest symmetry. Here we extend this approach to N $$ \mathcal{N} $$ = (2, 2) superspace providing a doubled formulation for bi ...

Worldsheet (anti)instanton bound states in type II on T 2
The 1/8 BPS D 6ℛ4 coupling in type II string theory compactified on T 2 receives contributions from worldsheet instantons and anti-instantons wrapping the T 2, up to genus three in string perturbation theory.

Vacua of ω-deformed SO(8) supergravity
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 ...

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

Superconformal duality-invariant models and N $$ \mathcal{N} $$ = 4 SYM effective action
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 ...
