Nature of problem:
The theoretical determination of cross sections in particle processes requires the calculation of radiative corrections. The most important contribution comes from the level of one-loop Feynman diagrams which arise from the model under consideration, usually the standard model of elementary particles.
This package is designed to evaluate automatically one-loop integrals. It is making use of the properties of R functions, a class of special functions which simplifies the evaluation of Feynman integrals.
The algebraic evaluation of a two-point function up to the rank 2 tensor on a VAX 4000-90 needs less than 20s.
