Fragmentation Functions for Pions, Kaons, Protons and Neutrons


Brief Description

Below you will find new sets of LO and NLO fragmentation functions (FF's) for pions, kaons and (for the first time) protons and neutrons. The FF's are obtained from fits to the newest data of charged hadron production from SLD, DELPHI, OPAL and ALEPH at the Z-boson resonance. We also included older data from TPC at lower cm energy to gain sensitivity to the scaling violation in fragmentation. The FF's are given in a parametrized form so they can be used conveniently without actually solving the DGLAP equations.
