New “electric” description of supersymmetric quantum chromodynamics

Responding to the recent claim that the origin of moduli space may be unstable in “magnetic” supersymmetric quantum chromodynamics (SQCD) with Nf≤3Nc/2 (Nc>2) for Nf flavors and Nc colors of quarks, we explore the possibility of finding nonperturbative physics for “electric” SQCD. We present a recently discussed effective superpotential for “electric” SQCD with Nc+2≤Nf≤3Nc/2 (Nc>2) that generates chiral symmetry breaking with a residual nonabelian symmetry of SU(Nc)L+R×SU(Nf−Nc)L×SU(Nf−Nc)R. Holomorphic decoupling property is shown to be respected. For massive Nf−Nc quarks, our superpotential with instanton effect taken into account produces a consistent vacuum structure for SQCD with Nf=Nc compatible with the holomorphic decoupling.
