Identified particle measurements at RHIC: elucidating hadronization mechanisms for bulk partonic matter
Paul Sorensen
Abstract
Measurements of identified particle momentum spectra at center of mass energy 200 GeV are reviewed. Emphasis is placed on the azimuthal dependence and the centrality dependence of hadron yields at intermediate transverse momentum (1.5 < pT < 5 GeV/c). The first measurements of the fourth harmonic term (v4) in the azimuthal variation of identified particle yields are shown. The recombination mechanism of hadron formation provides a consistent description of the dependence of these measurements on particle-type.
