Description
We compute planar and nonplanar twoloop doublebox integrals required for NNLO electroweak corrections to Møller scattering, with three massive Z bosons exchanged between the fermion lines. These integrals involve integration kernels tied to elliptic, K3 and genus two geometries. By applying a new εfactorization method for the associated differential equations, we obtain closedform results in terms of iterated integrals over those kernels.
