Abstract
We study the complex deformations of orientifolds of D3-branes at toric CY singularities, using their description in terms of dimer diagrams. We describe orientifold quotients that have fixed lines or fixed points in the dimer, and characterize the possibilities to deform them in terms of the behaviour of zig-zag paths under the orientifold symmetry. The resulting models are holographic duals to warped throats with orientifold planes. Our systematic construction provides a general class of configurations which includes models recently appeared in the context of de Sitter uplift by nilpotent goldstino or dynamical supersymmetry breaking.
Highlights
We provide general background on dimer models, starting with their basic features, their mirror description and afterwards review how complex deformations of toric singularities are described in this context
The flexibility of warped throats as local configurations able to generate hierarchies in string compactifications motivates the systematic exploration of possible throat geometries and their properties
This motivates the development of new tools to characterize orientifolded warped throats, a task we have addressed in the present paper
Summary
We provide general background on dimer models, starting with their basic features, their mirror description and afterwards review how complex deformations of toric singularities are described in this context. We mention the general features of orientifolds of dimer models that will be relevant in our analysis
