Description

The influence of vacuum polarization on a confinement picture is discussed. The pair-production effects on the potential between two external charges are analyzed in the Schwinger model. Depending on the order of magnitude of the fermion mass, one obtains two clearly distinguished behaviors for the potential reflecting screening or confinement. In exceptional situations one finds colorless ''quarks.''
