1. Supersymmetric sphaleron configurations as the origin of the perplexing ANITA events / Anchordoqui, Luis A. ; Antoniadis, Ignatios
The ANITA experiment has observed two air shower events with energy ∼500PeV emerging from the Earth with exit angles of ∼30∘ . [...]

2. Perturbative moduli stabilisation in type IIB/F-theory framework / Antoniadis, Ignatios ; Chen, Yifan ; Leontaris, George K.
We propose a new mechanism of (geometric) moduli stabilisation in type IIB/F-theory four-dimensional compactifications on Calabi–Yau manifolds, in the presence of 7-branes, that does not rely on non-perturbative effects. [...]

3. All partial breakings in N = 2 $$ \mathcal{N}=2 $$ supergravity with a single hypermultiplet / Antoniadis, Ignatios ; Derendinger, Jean-Pierre ; Petropoulos, P. ; Siampos, Konstantinos
We consider partial supersymmetry breaking in N = 2 $$ \mathcal{N}=2 $$ supergravity coupled to a single vector and a single hypermultiplet. [...]

4. The effective supergravity of little string theory / Antoniadis, Ignatios ; Delgado, Antonio ; Markou, Chrysoula ; Pokorski, Stefan
In this work we present the minimal supersymmetric extension of the five-dimensional dilaton-gravity theory that captures the main properties of the holographic dual of little string theory. [...]

5. A string realisation of Ω -deformed Abelian N=2⁎ theory / Angelantonj, Carlo ; Antoniadis, Ignatios ; Samsonyan, Marine
The N=2⁎ supersymmetric gauge theory is a massive deformation of N=4 , in which the adjoint hypermultiplet gets a mass. [...]

6. Nonlinear N = 2 $$ \mathcal{N}=2 $$ global supersymmetry / Antoniadis, Ignatios ; Derendinger, Jean-Pierre ; Markou, Chrysoula
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. [...]
