Abstract
We propose the use of D-brane realizations of Dynamical Supersymmetry Breaking (DSB) gauge sectors as sources of uplift in compactifications with moduli stabilization onto de Sitter vacua. This construction is fairly different from the introduction of anti D-branes, yet allows for tunably small contributions to the vacuum energy via their embedding into warped throats. The idea is explicitly exemplified by the embedding of the 1-family $SU(5)$ DSB model in a local warped throat with fluxes, which we discuss in detail in terms of orientifolds of dimer diagrams.

Field theory, since it arises from the spontaneous susy breaking dynamics of strongly coupled gauge theory sectors on D3-branes (DSB sectors)

Summary
The gauge theories for D3-branes at toric CY threefold singularities are nicely encoded in a combinatorial graph known as dimer diagram [29, 30] (see [31, 32] and references therein). They are (bipartite) graph tilings of T2, whose faces correspond to gauge factors, 1Another mechanism to uplift the cosmological constant via DSB in the Large Volume Scenario was proposed in [13]. There are two kinds of orientifold quotients, classified by their fixed sets being lines or points Two such orientifolds of the conifold theory are shown in figure 2. Faces and edges not mapped to themselves by the orientifold, combine with their images and descend to U(na) gauge factors and bi-fundamental matter multiplets in the orientifold theory
