No. 1002 (00067) Family name : Tord Given name : Riemann, Affiliation : Theory Group, DESY Abbreviation : DESY E-mail address : Tord.Riemann@desy.de Title : Towards automated use of Diana Authors : Riemann, T. Abstract : We describe structure and use of a software package for the calculation of one- and two-loop Feynman diagrams. The package reads output from Diana (and also from qgraph, for which Diana is an interface) and provides Fortran routines for a numerical calculation of cross-sections.
