Duality in nonsupersymmetric M-theory QCD

The curves that describe the M-theoretic extension of type IIA string configurations with non-supersymmetric field theories on their surface exhibit a duality map. The map suggests a continued link between an $\mathrm{SU}\mathrm{}\left(N\right)\mathrm{}$ gauge theory with $F$ flavors and an $\mathrm{SU}\left(F-N\right)$ gauge theory with $F$ flavors (the duality of supersymmetric QCD) even when the gaugino mass is taken to infinity. Within the context of the field theory such a duality only continues to make sense if the scalar fields remain light. We discuss the difficulties of decoupling the scalars within this framework.
