Screening and confinement in large N_{f} QCD _{2} and in N = 1 SYM _{2}
Abstract
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.
