Primary Feynman rules to calculate the epsilon-dimensional integrand of
any 1-loop amplitude    [PDF]

R. Pittau

When using dimensional regularization/reduction the epsilon-dimensional
numerator of the 1-loop Feynman diagrams gives rise to rational contributions.
I list the set of fundamental rules that allow the extraction of such terms at
the integrand level in any theory containing scalars, vectors and fermions,
such as the electroweak standard model, QCD and SUSY.
