Third-order mixed electroweak-QCD corrections to the W-boson mass prediction from the muon lifetime

Ievgen Dubovyk, Ayres Freitas, Janusz Gluza +1

We present the calculation of the so far missing $\mathcal{O}({\alpha }^2{\alpha }_{\mathrm{s}})$ corrections to the quantity $\Delta r$, which relates the Fermi constant to the W-boson mass, and enables pre…
