Journal reference: Comput. Phys. Commun. 85(1995)153
Programming language: Maple.
Computer: VAX 4000-90.
Operating system: VMS, MS-DOS 6.0.
Keywords: Particle physics, Elementary, Qed, Electroweak theory, Feynman diagrams, One-loop corrections, Renormalization.
Classification: 11.4.

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 evaluation of a two-point function up to the rank 2 tensor on a VAX 4000-90 needs less than 20s.
