Description
We suggest a new approach for the automatic and fully numerical evaluation
of one-loop scattering amplitudes in perturbative quantum field theory. We
use suitably formulated dispersion relations to perform the calculation as
a convolution of tree-level amplitudes. This allows to take advantage of
the iterative numerical algorithms for the evaluation of leading order
matrix elements
