Automated use of DIANA for two-fermion production at colliders
Abstract
We describe packages for the calculation of radiative corrections to two-fermion production at colliders. The packages use DIANA, and also QGRAF, FORM, Fortran, and further unix/linux tools. The one-loop calculations in the Standard Model are highly automatized with the package aITALC. Further, the automatic determination of all the matrix elements for two-loop corrections to massive Bhabha scattering in QED and the classification of their topologies and prototypes is done with DIANA. A generalization to the Standard Model is straightforward.
