Description
The gluon propagator in the (1+1)-dimensional QCD with Nf flavors of massless quarks is investigated in the large Nf limit. We use a three-parameter family of Lorentz covariant gauge fixing terms to show that the leading singularity of the propagator at the (renormalized) Schwinger mass is gauge independent. (orig.)
