Precision determination of alpha(S)(M-Z) using an unbiased global NLO parton set
- Abstract:
-
We determine the strong coupling αs from a next-to-leading order analysis of processes used for the NNPDF2.1 parton determination, which includes data from neutral and charged current deep-inelastic scattering, Drell-Yan and inclusive jet production. We find αs(MZ)=0.1191±0.0006exp, where the uncertainty includes all statistical and systematic experimental uncertainties, but not purely theoretical uncertainties, which are expected to be rather larger. We study the dependence of the results on...
