Abstract: (Elsevier)
When the background field method is used in superspace the resulting covariant Feynman rules simplify the evaluation of supergraphs. We describe methods that lead to additional simplifications in both SSYM and supergravity. The number of supergraphs is smaller and the use of covariant D-algebra implies that they do not depend on the YM spinor connection Γ α , or vielbein E M > α and are therefore more convergent.- SUPERSYMMETRY
