Revisiting unidentified charged-hadron fragmentation functions with modern COMPASS SIDIS multiplicities

Author(s): Maryam Soleymaninia, Hamzeh Khanpour, Hubert Spiesberger, Majid Azizi, Michael Klasen, and Hadi Hashamipour (HAPS Collaboration)We present HAPS-hFF1.0, a new global QCD analysis of unidentified charged-hadron fragmentation functions (FFs) using single-inclusive electron-positron annihilation (SIA) data together with the modern COMPASS semi-inclusive deep-inelastic scattering (SIDIS) multiplicities. The COMPASS input consists…[Phys. Rev. D 114, 054013] Published Tue Sep 08, 2026
