title = "How to calculate 35 640 O(α5) Feynman diagrams in less than an hour",
abstract = "We present a powerful method for evaluating Feynman amplitudes involving fermions which interact through gauge bosons. Implementing our procedure on a computer, we have evaluated the O(αs4) and O(αs5) five- and six-quark scattering amplitudes required to predict exclusive hadron scattering amplitudes in QCD.",
