From obscurity to two-loop respectability: progress in the light-cone gauge
We evaluate the complete two-loop correction Sigma /sub 2/ to the quark propagator in the light-cone gauge. It is shown that the total divergent contribution to Sigma /sub 2/ is a local function of the external momentum p, even off the mass-shell, since all nonlocal divergent terms cancel exactly. O...

| description | We evaluate the complete two-loop correction Sigma /sub 2/ to the quark propagator in the light-cone gauge. It is shown that the total divergent contribution to Sigma /sub 2/ 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 renormalizability of QCD in the light-cone gauge to two loops. (9 refs). |
