SummaryPaper and pencil are no longer adequate for the prediction of measurements at high-energy colliders, such as the Large Hadron Collider currently under construction at CERN. These predictions are essential for testing the present theories of elementary particles, i.e. the fundamental laws of nature, yet their computation without automated steps is quite involved and error-prone. This article introduces the necessary computational methods and shows their implementation in a computer program on the example of the FeynArts, FormCalc, and LoopTools packages, which are being developed at the MPI. With the automation thus achieved, results can be obtained in minutes that were previously in the domain of man-years.
