Notes on graphical functions with numerator structure
Oliver Schnetz, Simon Theil
TL;DR
This paper extends the theory of graphical functions from scalar theories to those involving spin, broadening the applicability of the framework in quantum field theory.
Contribution
It introduces a generalization of graphical functions to include theories with spin, which was not previously addressed.
Findings
Extended graphical functions to theories with spin
Provided new mathematical tools for spinor theories
Enhanced understanding of graphical functions in complex theories
Abstract
In these notes we generalize the theory of graphical functions from scalar theories to theories with spin.
