A PHENIX perspective on soft observables in Heavy Ion Collisions
نویسنده
چکیده
We present an overview of measurements from the PHENIX experiment focusing on soft observables in nucleus-nucleus collisions. The excellent particle identification of the PHENIX detector at low and intermediate transverse momentum provide an extensive set of measurements in nucleus-nucleus collisions and baseline measurements in p+p and d+Au collisions. Thermalized particle spectra, strong elliptic and radial flow, and HBT measurements reveal the global features of the hot QCD medium produced at RHIC energies while fluctuation measurements probe critical behavior near a phase transition. Collectively these measurements reveal a hot, dense medium with partonic degrees of freedom undergoing a locally-thermalized hydrodynamic expansion.

The PHENIX Potential in the Search for the QCD Critical Point
With the measurement of several observables at SPS energies that demonstrate non-monotonic behavior as a function of centrality and √ sNN , there is growing interest in pursuing a scan of relativistic heavy ion collisions at low energies at the Relativistic Heavy Ion Collider. The capabilities of the PHENIX experiment to take quality measurements at low RHIC energies is described and directly d...
متن کاملHigh-pT Particle Production in PHENIX
It has been established that "hard probes", observables involving high-momentum transfer, provide useful tools for studying the hot, dense medium created in nucleus-nucleus collisions at RHIC. The nuclear modification factor, azimuthal correlations, direct photon production, as well as the dependence of the nuclear modificaton factor on centrality and angle with respect to the reaction plane ar...

The PHENIX Experiment at the Relativistic Heavy Ion Collider has made measurements of event-by-event fluctuations in the net charge, the mean transverse momentum, and the charged particle multiplicity as a function of collision energy, centrality, and transverse momentum in heavy ion collisions. The results of these measurements will be reviewed and discussed.. 1. Introduction The PHENIX experi...
متن کاملCharm and leptons
Observables related to charm and leptons are of great relevance in heavy ion collisions considering the significant information that they have revealed over the last years. The low mass dielectron yield measured by the CERES collaboration has provided evidence for in-medium effects on the ρ meson. The J/ψ suppression pattern observed by the NA50 collaboration is believed to be an important sign...
متن کاملSoft-hadronic Observables for Relativistic Heavy-ion Collisions at Rhic and Lhc * * *
The relativistic hydrodynamics together with the single-freeze-out statistical hadronization model is used to describe the midrapidity hadron production in ultra-relativistic heavy-ion collisions at RHIC and LHC. At the highest RHIC energy our approach gives a quite satisfactory global description of soft hadronic observables including the HBT radii. With the increased initial energy, from RHIC...
