Fate of Chiral Symmetries in Supersymmetric Quantum Chromodynamics

Abstract

In supersymmetric quantum chromodynamics with Nc-colors and Nf-flavors of quarks, our effective superpotential provides the alternative description to the Seiberg's N=1 duality at least for Nf>=Nc+2, where spontaneous breakdown of chiral symmetries leads to SU(Nc)L+RxSU(Nf-Nc)LXSU(Nf-Nc)R as a nonabelian chiral symmetry. 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.
