Description

We compute the mixed two-loop electroweak and QCD corrections to hadronic W boson decays within the Standard Model. The optical theorem is applied to the W boson two-point function. The multi-scale integrals are computed with the help of asymptotic expansions which factorize the three-loop diagrams into one- and two-loop vacuum and propagator-type integrals.
