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