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 ( p T ) range. We present STAR results of identified charged pions, protons and antiprotons up to transverse momentum of 12 GeV / c in Au+Au, pp and d+Au collisions at the s N N = 200 GeV . Spectra, ratios, and nuclear modification factors, and their comparisons to jet fragmentation, partonic energy loss, and coalescence/recombination models are discussed.
