Manuscript Title: A new method for computing one-loop integrals. | ||

Authors: L. Brucher, J. Franzkowski, D. Kreimer | ||

Program title: ONELOOP.MA | ||

Catalogue identifier: ACVW_v1_0Distribution format: gz | ||

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. |
