Abstract
We have examined the structure of leading infrared divergences of the -matrix elements for nonexceptional momentum configurations for an arbitrary number of massive quarks and color-singlet external sources in non-Abelian gauge theories. it is shown that the sum of all these divergences satisfies a simple differential equation with respect to the space-time dimension as an infrared cutoff.
