FeynCalc manual (development version)

$KeepLogDivergentScalelessIntegrals

$KeepLogDivergentScalelessIntegrals is an experimental global option that forces FeynCalc not to set 1-loop integrals of type 1/q4\frac{1}/{q^4} to zero. This is useful when one has to explicitly distinguish between IR- and UV-divergences in dimensional regularization. Notice that OneLoop is not guaranteed to respect this option.
