Fate of Chiral Symmetries in Supersymmetric Quantum Chromodynamics

  • TOKAI-HEP/TH-0003 (Aug., 2000) with Mr. Y. Honda (Talk given by M.Y. at XXXth International Conference on High Energy Physics, July 27-August 2, 2000, Osaka, Japan)

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+R xSU(Nf-Nc)L xSU(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.
