Abstract

Parametrizations of fragmentation functions (FFs) from e⁺-e^- and p-p collisions are combined with a parton spectrum model in a pQCD folding integral to produce minimum-bias \em fragment distributions. A model of in-medium FF modification is included. Calculated fragment distributions are compared with \em hard components from p-p and Au-Au p_t spectra. Data are well described by pQCD over a large kinematic region for a range of Au-Au centralities.
