Effective Lagrangian for supersymmetric quantum chromodynamics and the problem of dynamical breaking of supersymmetry

In the framework of $1/N$ expansion the effective me sonic action for supersymmetric (SUSY) QCD is constructed. The absence of dynamic spontaneous supersymmetry breaking is demonstrated. An explicit expression for the low-energy action is obtained which takes into account anomalies and represents a supersymmetric generalization of the Weinberg–Wess–Zumino–Witten action.
