Charge Particle Multiplicity and Transverse Energy Measurements in Au-Au collisions in PHENIX at RHIC

We present results on charged particle (dNch/dη) and transverse energy densities (dET/dη) measured at mid-rapidity in Au-Au collisions at √ s NN =200 GeV. The mean transverse energy per charged particle is derived. The results are presented as a function of centrality, which is defined by the number of participating nucleons (Np), and compared to results obtained in Au-Au collisions at √ s NN =...

Measurements from PHENIX

We present recent high transverse momentum measurements by the PHENIX experiment for Au+Au and p+p collisions at √ s N N = 200 GeV at the Relativistic Heavy Ion Collider (RHIC). We show particle spectra for neutral pions and charged hadrons, define and show the nuclear modification factor, and discuss particle composition. By means of the nuclear modification factor, we observe a suppression fa...

Two Particle Azimuthal Correlation Measurements in PHENIX

Two particle azimuthal correlation functions are presented for charged hadrons produced in Au + Au collisions at RHIC (√ s NN = 200 GeV). The correlation functions indicate sizeable asymmetries and anisotropies. The trend of the asymmetries is compatible with the presence of emission patterns associated with mini-jets. The magnitude and the trend of the differential anisotropies v 2 (p T) and v...

PHENIX: measurements and jet contribution simulations

Small, but significant non-random fluctuations in event-by-event average pT have been observed in Au+Au collisions at √ sNN = 200 GeV by the PHENIX collaboration. These are consistent with being caused by correlations due to jets at large pT , where the measured suppression must be included to reproduce the centrality dependence of the non-random fluctuations. 1. The event-by-event average pT d...
