摘要：

We study chiral symmetry breaking in quenched QED4, using a vertex ansatz recently proposed by Curtis and Pennington. Bifurcation analysis is employed in a general covariant gauge to investigate the gauge-dependence of the critical coupling for chiral symmetry breakdown. This turns out to be relatively minor, justifying the use of this vertex.
