Abstract: We suggest a new approach for the automatic and fully numerical evaluation ofone-loop scattering amplitudes in perturbative quantum field theory. We usesuitably formulated dispersion relations to perform the calculation as aconvolution of tree-level amplitudes. This allows to take advantage of theiterative numerical algorithms for the evaluation of leading order matrixelements.
