Global observables and identified hadrons in the phenix experiment at RHIC
(2004) 18th Annual Lake Louise Winter Institute p.230-235- Abstract
- The PHENIX experiment is one of the two large experiments at RHIC. It addresses most of the signals suggested from the Quark-Gluon Plasma. This paper focuses on the measurements of global observables and identified hadron spectra and particle ratios from the two first runs with Au+Au collisions at 130A GeV and 200A GeV. The energy density reached in the most central collisions is about 5 GeV/fm(3). The spectral shape of the transverse momentum spectra as well as the < PT > dependence on centrality indicate a strong collective expansion of the system in central collisions. The observed number of protons and p is about the same indicating that we are approaching a net baryon free region at mid rapidity. A larger number of protons than... (More)
