Fragmentation Functions for Light Charged Hadrons with Complete Quark Flavour Separation
S. Albino, B. A. Kniehl, G. Kramer
Abstract
We present new sets of next-to-leading order fragmentation functions describing the production of charged pions, kaons and protons from the gluon and from each of the quarks, obtained by fitting to all relevant data sets from e+ e- annihilation. The individual light quark flavour fragmentation functions are obtained phenomenologically for the first time by including in the data the light quark tagging probabilities obtained by the OPAL Collaboration.
