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.

Solution method:
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.

Running time:
The algebraic or numeric evaluation of a three-point function up to the rank-3-tensor on a DEC Alpha 8400 needs less than 2s.
