Abstract: (Elsevier)

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(α s 4 ) and O(α s 5 ) five- and six-quark scattering amplitudes required to predict exclusive hadron scattering amplitudes in QCD.
