Improved strong coupling determinations from hadronic decays of electroweak bosons at N${}^3$LO accuracy

David d'Enterria, Villads Jacobsen

We present two new extractions of the QCD coupling constant at the Z pole, ${\alpha }_S(m_Z)$, from detailed comparisons of inclusive W and Z hadronic decays data to state-of-the-art pertu…
