The anomaly-matching is ensured by the presence of Nambu-Goldstone superfields associated with this breaking and the instanton contributions are properly equipped in the effective superpotential.Talk at XXXth International Conference on High Energy Physics, July 27-August 2, 2000, Osaka, JapanHigh Energy Physics - Theorytext
