Abstract
Conditions are stated, which are sufficient for the heavy-mass-suppres sion of BPHZL-subtracted Feynman-integrals containing propagators of ' 'heavy fields''. This result generalizes the Decoupling Theorems of Am bjorn, Manoukian and Landsman to cases, where massless fields (e.g., g auge fields) are present. (C) 1996 Academic Press, Inc.
