Strong coupling determination from W and Z decays at N3LO
We present two new extractions of the QCD coupling at the Z pole $\alphasmZ$ from comparisons of experimental data on inclusive W and Z bosons hadronic decays to state-of-the-art perturbative QCD (pQCD) calculations at N$^{3}$LO accuracy including, in the Z boson case, also the full two-loop elect...
