Precision NNLO determination of α s(M Z) using an unbiased global parton set
We determine the strong coupling α s at NNLO in perturbative QCD using the global dataset input to the NNPDF2.1 NNLO parton fit: data from neutral and charged current deep-inelastic scattering, Drell-Yan, vector boson production and inclusive jets. We find α s(M Z)=0.1173±0.0007 stat, where the stat...
