Open string instantons and superpotentials
The authors study the F-terms in N = 1 supersymmetric, d = 4 gauge theories arising from D(p + 3)-branes wrapping supersymmetric p-cycles in a Calabi-Yau threefold. If p is even the spectrum and superpotential for a single brane are determined by purely classical ({alpha}{prime} {r{underscore}arrow} 0) considerations. If p = 3, superpotentials for massless modes are forbidden to all orders in {alpha}{prime} and may only be generated by open string instantons. For this latter case the authors find that such instanton effects are generically present. Mirror symmetry relates even and odd p and thus perturbative and nonperturbative superpotentials; the authors provide a preliminary discussion of a class of examples of such mirror pairs.
