We present the calculation of the mixed two-loop QCD/electroweak 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.

Renormalization of mixing angles and computation of the hadronic $W$ decay widths
A basis-choice variant of the on-shell renormalization scheme eliminates mixing-matrix counterterms and is used to compute consistent 1-loop hadronic W decay widths in the SM.
