摘要
We give some details of the recently completed calculation of the full two-loop fermionic corrections to the lept effective leptonic weak mixing angle, sin(2) 0(eff)(lept). 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.
