| dc.description.abstract | The QCD coupling αs is determined at NLO*+NMLLA accuracy from the comparison of experimental jet data to theoretical predictions of the energy-evolution of the parton-to-hadron fragmentation function moments (multiplicity, peak, width, skewness) at low fractional hadron momentum z. From the existing e+e− and e±p jet data, we obtain αs(m2 Z ) = 0.1195±0.0021(exp)+0.0015 −0.0 (scale) at the Z mass. The uncertainties of the extracted αs value are discussed. | |
