Journal reference: Comput. Phys. Commun. 107(1997)281 | ||

Programming language: Maple. | ||

Computer: DEC Alpha 8400. | ||

Operating system: Unix (Linux 2.0), VMS 6.2, MS-DOS 6.0. | ||

RAM: 8M words | ||

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