Determination of the strong coupling constant ${\alpha_S}(m_{\mathrm{Z}})$ from measurements of inclusive $\mathrm{W}^{\pm}$ and $Z$ boson production cross sections in proton-proton collisions at $\sqrt{s} = $ 7 and 8 TeV / CMS Collaboration
Twelve measurements of inclusive cross sections of $\mathrm{W^{\pm}} $ and $\mathrm{Z}$ boson production, performed in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, are compared with perturbative quantum chromodynamics calculations at next-to-next-to-leading order (NNLO) accuracy obtained with the CT14, HERAPDF2.0, MMHT14, and NNPDF3.0 parton distribution functions (PDFs).
