    The impact of data from future lepton colliders on light hadrons fragmentation functions by Bin Zhou, Jun Gao

    Published 2025-02-01
    “…The high luminosity and high energies of future lepton colliders allow for quark flavor separations and ensure a precise determination of FFs based solely on data from electron-positron collisions. We find that either the CEPC, FCC-ee or ILC can significantly reduce the uncertainties of FFs in a wide kinematic range, compared to the NPC23 set obtained with a global analysis to current world data. …”
