Graphical functions in parametric space

Marcel Golz, Erik Panzer, Oliver Schnetz

Graphical functions are positive functions on the punctured complex plane which arise in quantum field theory. We generalize a parametric integral repr…

Feynman integrals and hyperlogarithms

Erik Panzer

We study Feynman integrals in the representation with Schwinger parameters and derive recursive integral formulas for massless 3- and 4-point functions. Properties of analytic (inc…
