Description
We give some details of the recently completed calculation of the full two-loop fermionic corrections to the effective leptonic weak mixing angle, sin2θefflept. Among others, we describe the C++ library DiaGen/IdSolver, which was used to reduce the two-loop light fermion vertex diagrams to linear combinations of master integrals with rational function coefficients.
