Description

Abstract: Two-loop non-planar master integrals are needed for the NNLO QCD 
corrections to diphoton and dijet production at hadron colliders. The 
top-sector topology contains an internal massive fermion loop and is known 
to contain elliptic curves. In this talk, I will first review the method of 
differential equations, and then discuss how to derive an ε-factorized 
differential equation for the elliptic sector within the Feynman integral 
family. To do so, I will explain how information from geometry can help to 
deal with the complexity of this multiscale problem. I will finally conclude 
with some outlooks.
