$\alpha_S$ from soft QCD jet fragmentation functions
We present an extraction of the QCD coupling $\alpha_s$ from the energy evolution of the first two moments (multiplicity and peak position) of the parton-to-hadron fragmentation functions at low fractional hadron momentum $z$. A fit of the experimental jet data, from $e^+e^−$ and deep-inelastic $e^{...
