Title: Extraction of pion non-perturbative fragmentation functions in ZM-VFNS

Abstract

We present pion non-perturbative fragmentation functions (non-pFFs) at next-to-leading order (NLO) obtained through a global fit to electron-positron annihilation data from CERN LEP1, SLAC SLC, DESY and KEK, using zero-mass variable-flavor-number scheme. We apply the obtained non-pFFs to predict the scaled-energy distribution of {pi}{sup {+-}} inclusively produced in top-quark decays. The results are in good agreement with the available theoretical models.
