One-loop Calculations in Light-cone Gauge 1

Loop calculations in light-cone gauge must confront many technical complexities. We offer here a compendium of detailed light-cone calculations in Yang-Mills theories (with no matter fields). We consistently regulate the p = 0 singularities through discretization of the p component of momentum. Although it is more cumbersome than the Mandelstam-Leibbrandt prescription, this choice has the virtue of employing only positive norm states, retaining manifest unitarity. Some of the results given here are useful for the forthcoming paper [1], specifically the results for the gluon self energy and one-loop vertex corrections.
