Diagrammatic Coaction of Two-Loop Feynman Integrals
Samuel Abreu, Ruth Britto, Claude Duhr +2
It is known that one-loop Feynman integrals possess an algebraic structure encoding some of their analytic properties called the coaction, which can be written in terms of Feynman…

Generalized hypergeometric functions and intersection theory for Feynman integrals
Samuel Abreu, Ruth Britto, Claude Duhr +2
Feynman integrals that have been evaluated in dimensional regularization can be written in terms of generalized hypergeometric functions. It is well known that properties of these…

The two-loop five-point amplitude in supergravity
Samuel Abreu, Lance J. Dixon, Enrico Herrmann +2
We compute the symbol of the two-loop five-point amplitude in supergravity. We write an ansatz for the amplitude whose rational prefactors are based on not only 4-di…
