Abstract

The screening nature of the potential between external quarks in massless SU(Nc)SU(N_c) QCD2QCD_2 is derived using an expansion in NfN_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.
