Graphical functions with spin

Abstract The theory of graphical functions is generalized from scalar theories to theories with spin, leading to a numerator structure in Feynman integrals. The main part of this article treats the case of positive integer spin, which is obtained from spin 1/2 theories after the evaluation of γ trac...
