Description

We present a powerful method for evaluating Feynman amplitudes involving fermions which interact thorugh gauge bosons. Implementing our procedure on a computer, we have evaluated the O(α4sub(s)) and O(α5sub(s)) five- and six-quark scattering amplitudes required to predict exclusive hadron scattering amplitudes in QCD.
