Abstract :
I will show examples of high momentum identified particle measurements in heavy ion collisions at RHIC energies. Identified particles enable us to probe the existence and the hadronization mechanisms of the produced partonic medium in the case of the formation of a Quark-Gluon-Plasma (QGP). Besides probing the features of the plasma we also learn about the in-medium parton fragmentation process. I propose future measurements at RHIC-II and LHC in order to determine the dynamic evolution of the system from partonic to hadronic degrees of freedom.
