Unoriented Quivers with Flavour

Understand

We discuss unoriented quivers with flavour that arise from D3-branes at local orbifold singularities, in the presence of Omega-planes and non-compact D7-branes.

• We produce a wide class of unoriented quiver gauge theories, including new instances of N=1 superconformal theories.
• We then consider unoriented D-brane instanton corrections of both `gauge' and `exotic' kinds.
• In particular, we show that conformal symmetry can be dynamically broken via the generation of exotic superpotentials.
