On different criteria for confinement

We compare two approaches in supersymmetric confinement, the Seiberg formulation and the superconvergence rule. For the latter, the critical point is γ00=0 in the Landau gauge. We find 4γ00=β0 is the critical point for most of confining theories without a tree-level superpotential in the Seiberg formulation, in particular, in the large Nc and Nf limit. We show how confining theories with a discrete symmetry and a tree-level superpotential connect these two critical points: the large and small discrete symmetry limits correspond to the critical points 4γ00=β0 and γ00=0, respectively.
