We provide further evidence for the screening behavior of massless SU(Nc) bosonized QCD by (i) computing the potential between external quarks, (ii) bosonizing also the external sources and analyzing the states of the combined system and (iii) using an expansion in Nf- the number of flavors. We write down novel "non-abelian Schwinger like" solutions of the equations of motion, compute their masses and argue that an exchange of massive modes of this type is associated with the screening mechanism. Confinement for massive dynamical fermions is shown using (ii) and (iii). We show the screening behavior of the N=1 super Yang Mills theory, by applying a point splitting method to the scalar current.
