Exploring Nuclear Matter at Extreme Temperatures and Densities: Results from the PHENIX Experiment at RHIC — •Klaus Reygers — Institut für Kernphysik, Westfälische Wilhelms-Universität, Münster, Germany
The Relativistic Heavy Ion Collider (RHIC) in Brookhaven/USA became operational in the summer of 2000. This machine collides gold ions at energies of up to √snn = 200 GeV. The primary objective of the experiments at RHIC is to study a form of nuclear matter in which quarks and gluons are no longer confined within hadrons. The PHENIX experiment consists of a multitude of specialized detector systems and is therefore capable of measuring a variety of observables. A selection of PHENIX results will be discussed in this talk. Among the presented results will be the centrality dependence of identified hadron spectra and data on the elliptic flow pattern of particle production. Furthermore hadron production at large transverse momenta will be discussed. A striking difference compared to results at lower energies is found - an observation that belongs to the most important results of the first RHIC beamtime.
