摘要：

We analyze coupled Dyson-Schwinger equations for massless fermion and photon propagators in QED4[N], taking proper account of charge renormalization. With one fermion flavor, we find a fixed point at an ultraviolet ''fine-structure constant'' of 2.10, corresponding to a phase transition (associated with the dynamical breaking of chiral symmetry) of mean-field type.
