Description
In this work, we have computed the planar and non-planar contributions to the Møller scattering with three massive $Z$ bosons exchanged between the fermion lines. These cases involve complicated geometries like curves of genus $2$ and $K3$ surfaces, which until recently remained inaccessible. We demonstrate how these can be tamed with a newly developed technique for $\varepsilon$-factorization of Feynman Integrals.
