Abstract
We evaluate the complete two-loop correction Ct to the quark propagator in the light-cone gauge. It is shown that the total divergent contribution to Ct is a local function of the external momentum p, even off the mass-shell, since all nonlocal divergent terms cancel exactly. Our results prove the r enormalizability of QCD in the light-cone gauge to two loops.
