• The 5-point tensors have the property that after insertion of the metric tensor $g^{\mu \nu}$ in terms of external momenta, all $g^{\mu \nu}$-contributions in the tensor decomposition cancel. If furthermore the tensors are contracted with external momenta, the inverse 5-point Gram determinant $()_5$ cancels automatically. If the remaining 4-point sub-Gram determinant ${s\choose s}_5$ is not small then this approach appears to be particularly efficient in numerical calculations. We also indicate… CONTINUE READING
