Dimers in a Bottle

Eduardo García-Valdecasas, Shani Meynet, Antoine Pasternak +1

We revisit D3-branes at toric CY singularities with orientifolds and their description in terms of dimer models. We classify orientifold actions on the dimer through smooth inv…

Dimers, Orientifolds and Anomalies

Riccardo Argurio, Matteo Bertolini, Sebastián Franco +4

We study gauge theories engineered via D-branes at orientifolds of toric singularities, where gauge anomalies are cancelled without the introduction of non-com…

Dimers, Orientifolds and Stability of Supersymmetry Breaking Vacua

Riccardo Argurio, Matteo Bertolini, Sebastián Franco +4

We study (orientifolded) toric Calabi-Yau singularities in search for D-brane configurations which lead to dynamical supersymmetry breaking at low energy. By exploiting dimer techn…

The Octagon and the Non-Supersymmetric String Landscape

Riccardo Argurio, Matteo Bertolini, Sebastián Franco +4

We present an orientifold of a toric singularity allowing for a configuration of fractional branes which corresponds to a gauge theory that dynamically breaks supersymmetry in a st…

On supersymmetry breaking vacua from D-branes at orientifold singularities

Riccardo Argurio, Matteo Bertolini, Shani Meynet +1

We present a large class of models of D-branes at (orientifold) Calabi-Yau singularities which enjoy dynamical supersymmetry breaking at low energy, by means of either the

Are there Goldstone bosons in ?

Riccardo Argurio, Daniel Naegels, Antoine Pasternak

We study the viability of spontaneous breaking of continuous symmetries in theories with Lifshitz scaling, according to the number of space-time dimensions and the dynamical sc…
