Uncertainties on the determination of the strong coupling alpha_s from the energy evolution of jet fragmentation functions at low z
The QCD coupling alpha_s 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 exi...
