摘要
We give a pedagogical introduction to D-brane instanton effects in vacuum configurations with open and unoriented strings. We focus on quiver gauge theories for unoriented D-branes at orbifold singularities and describe in some detail the Z3 case, where both gauge and exotic instantons can generate non-perturbative super potentials, and the Z5 case, where supersymmetry breaking may arise from the combined effect of gauge instantons and a FI D-term.
