D-brane instantons as gauge instantons in orientifolds of chiral quiver theories
D-brane instantons as gauge instantons in orientifolds of chiral quiver theories
Systems of D3-branes at orientifold singularities can receive non-perturbative D-brane instanton corrections, inducing field theory operators in the 4d effective theory. In certain non-chiral examples, these systems have been realized as the infrared endpoint of a Seiberg duality cascade, in which the D-brane instanton effects arise from strong gauge theory …
