7. Cuts and Feynman amplitudes beyond polylogarithms

Lorenzo Tancredi (KIT Karlsruhe)

03/05/2018, 09:30

In this talk I will present some of the newest advancements in the calculation of multiloop Feynman amplitudes beyond multiple polylogarithms. In particular, I will show how to solve higher order irreducible differential equations for non-polylogarithmic Feynman integrals and how to write their solution in terms of a suitable basis of functions. I will also comment on the difficulties in...

11. Automated extraction of UV counterterms for arbitrary local operators

Dr Ben Ruijl (ETH Zurich)

03/05/2018, 12:00

Computing the anomalous dimensions of local composite operators present in both renormalisable and non-renormalisable QFTs is generally challenging due to the presence of many scales and loops. In this talk we present an extension of the local R* method which fully automates this task. By extending the local R* operation to arbitrary QFTs we, transform this problem to one of computing massless...
