"Bootstrapping 5-loop p-Integrals" by Alessandro Georgoudis (Uppsala)

Tuesday, May 22, 2018 - 4:00pm to 5:00pm
TEP Seminar

Computing higher loops Feynman Integrals is not an easy task. In this talk I will present a method we developed to obtain expansions of massless two-point integrals in position space by exploiting the constraints implied by symmetries of the asymptotic expansion of conformal four-point integrals and IBP identities. Together with parametric integration of few integrals, we are able to fix the expansions of 170 genuine five-loop master integrals. In particular,we computed the expansions of all planar master integrals up to transcendental weight 9.
