摘要：

The screening nature of the potential between external quarks in massless SU(N-c) QCD(2) is derived using an expansion in N-f - the number of flavors. Applying the same method to the massive model, we find a confining potential. We consider the N = 1 super Yang Mills theory, reveal certain problematic aspects of its bosonized version and show the associated screening behavior by applying a point splitting method to the scalar current.
