Renormalization group functions for the Wess-Zumino model: up to 200 loops through Hopf algebras
Marc Bellon, Fidel A. Schaposnik
We obtain the contributions to the renormalization group functions of all the diagrams containing the unique one-loop primitive divergence of a simple supersymmetric Wess--Zumino m…

Higher loop renormalization of a supersymmetric field theory
Marc Bellon, Gustavo S. Lozano, Fidel A. Schaposnik
Using Dyson--Schwinger equations within an approach developed by Broadhurst and Kreimer and the renormalization group, we show how high loop order of the renormalization group coef…
