Screening and confinement in large Nf QCD2 and in N = 1 SYM2 Original Research Article

The screening nature of the potential between external quarks in massless SU(Nc) QCD2 is derived using an expansion in Nf - 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.
