An integrated tool for loop calculations: aITALC

Abstract
aITALC, a new tool for automating loop calculations in high energy physics, is described. The package creates Fortran code for two-fermion scattering processes automatically, starting from the generation and analysis of the Feynman graphs. We describe the modules of the tool, the intercommunication between them and illustrate its use with three examples.

Title of program: aITALC version 1.2.1
Catalogue Id: ADWO_v1_0

Nature of problem
Calculation of differential cross sections for e + e - annhilation in one-loop approximation.
