Elliptic leading singularities and canonical integrands
Ekta Chaubey, Vasily Sotnikov
In the well-studied genus zero case, bases of integrands with integer leading singularities define Feynman integrals that automatically satisfy differential equati…

Two-loop non-planar four-point topology with massive internal loop
Taushif Ahmed, Ekta Chaubey, Mandeep Kaur +1
We study a set of two-loop non-planar master integrals needed for the NNLO QCD corrections to diphoton and dijet production at hadron colliders. The top-sector topology contains an…
