Abstract :
Heavy ion collisions at RHIC create a hot and dense medium that exhibits novel properties. Study of these properties and hadronization mechanisms of the medium requires identified particle results over wide transverse momentum (pT) range. We present STAR results of identified charged pions, protons and antiprotons up to transverse momentum of View the MathML source in Au+Au, pp and d+Au collisions at the View the MathML source. Spectra, ratios, and nuclear modification factors, and their comparisons to jet fragmentation, partonic energy loss, and coalescence/recombination models are discussed.
