Abstract

Hadron production has been calculated in a pQCD improved parton model for pp, dA and heavy ion collisions. We applied KKP and AKK fragmentation functions. Our jet fragmentation study shows, that hadron ratios at high p_T depend on quark contribution mostly and less on the gluonic one. This finding can be seen in jet-energy loss calculations, also. We display the suppression pattern on different hadron ratios in PbPb collisions at LHC energies.
