Abstract
We adapt the Newman-Penrose tetrad formalism to a systematic and efficient evaluation of Feynman integrals in the light-cone gauge. Our procedure exploits the traditional assumptions of locality and power counting as well as the useful tensor technique. It is shown that this program yields the same results as the much lengthier Feynman parameter method. There are no double poles to one-loop order.Keywords
