Challenges for analytic calculations of the massive three-loop form factors

Year: 2024

Type: conference-paper

Abstract: The calculation of massive three-loop QCD form factors using in particular the large moments method has been successfully applied to quarkonic contributions in [1]. We give a brief review of the different steps of the calculation and report on improvements of our methods that enabled us to push forward the calculations of the gluonic contributions to the form factors.
