Eight loops gamma in phi^4

Oliver Schnetz

Abstract: We report on a recent calculation of the anomalous dimension gamma in phi^4 theory to loop order eight. The calculation uses graphical functions and we focus on the extension of graphical functions to non-integer dimensions (which is necessary as a means of regularization of divergent Feynman integrals).
