ONE-LOOP INTEGRALS REVISITED - THE 3-POINT FUNCTIONS

This paper presents results concerning a new calculation of the well-k nown n-point scalar and tensor functions. In this paper we treat the t hree-point functions. we give a systematic reduction to a certain clas s of functions which minimizes the effort for calculating scalar and t ensor integrals drastically. We avoid standard techniques such as Feyn man parametrization and Wick rotation.
