| Abstract: | Conditions are stated, which are sufficient for the heavy-mass-suppression of BPHZL- subtracted Feynman-integrals containing propagators of “heavy fields”. This result generalizes the Decoupling Theorems of Ambjørn, Manoukian and Landsman to cases, where massless fields (e.g., gauge fields) are present. |
