oneloop 2.0 — A program package calculating one-loop integrals
Description
Abstract We present an improved version of our program package oneloop which — written as a package for MAPLE (Char, Geddes, Gonnet, Leong, Monagan, Watt, MAPLE V Language and Library Reference Manuals) — solves one-loop Feynman integrals. The package is calculating one-, two- and three-point functions both algebraically and numerically to any tensor rank. In addition to the original version, oneloop 2.0 also calculates infrared divergent integrals. Higher powers of propagator terms and the O(ε) parts... Title of program: oneloop.ma, version 2.0 Catalogue Id: ACVW_v2_0 [ADGT] 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.
