Measurement of high-pT hadrons at RHIC-PHENIX
Tadaaki Isobe
Abstract
Measurements from the RHIC experiments show a strong suppression in the yield of high-pT single hadrons and a clear reduction in strength of the di-jet signal in two-hadron azimuthal-angle correlation functions in central Au+Au collisions at RHIC. These measurements should provide direct information on the properties of the medium within which hard-scattered partons propagate. The PHENIX preliminary results on single high-pT hadron production and on particle azimuthal correlations are shown. The properties of the medium created in relativistic heavy ion collisions are discussed based on the results.
