Precision determination of the strong coupling constant within a global PDF analysis
We present a determination of the strong coupling constant $\alpha _s(m_Z)$ based on the NNPDF3.1 determination of parton distributions, which for the first time includes constraints from jet production, top-quark pair differential distributions, and the Z $p_T$ distributions using exact NNLO theory...
