Abstract
We re-examine Quantum Electrodynamics (QED) with massless electron as a finite quantum field theory as advocated by Gell-Mann-Low, Baker-Joh nson, Adler, Jackiw and others. We analyze the Dyson-Schwinger equatio n satisfied by the massless electron in finite QED and conclude that t he theory admits no nontrivial eigenvalue for the fine structure const ant.
