(sNN)=200GeV Au+Au collisions in the PHENIX Experiment at RHIC
The first measurement of the dielectron continuum at RHIC energies was performed by the PHENIX experiment for Au+Au collisions at √ sNN= 200 GeV. Mass spectra for different centralities are presented and compared with the expectations from hadron decays.
متن کاملNeutral Meson Measurement at Phenix
Measurements from the RHIC experiments show strong suppression of high-pT hadrons in central Au+Au collisions. The PHENIX experiment has observed strong suppression of π0 and charged hadron yields in central Au+Au collisions for pT > 5 GeV/c regardless of pT and particle species. The observed suppression is interpreted in terms of energy loss of quarks in a high-density medium. The PHENIX Year-...
متن کاملLow-mass dielectrons from the PHENIX experiment at RHIC
The production of the low-mass dielectrons is considered to be a powerful tool to study the properties of the hot and dense matter created in the ultra-relativistic heavy-ion collisions. We present the preliminary results on the first measurements of the low-mass dielectron continuum in Au+ Au collisions and the φ meson production measured in Au+Au and d+Au collisions at √ s NN = 200 GeV perfor...
متن کامل2 00 5 Nuclear modification and elliptic flow measurements for φ mesons at √ s NN = 200 GeV d + Au and Au + Au collisions by PHENIX
We report the first results of the nuclear modification factors and elliptic flow of the φ mesons measured by the PHENIX experiment at RHIC in high luminosity Au+Au collisions at √ sNN = 200 GeV. The nuclear modification factors RAA and RCP of the φ follow the same trend of suppression as π’s in Au+Au collisions. In d+Au collisions at √ sNN = 200 GeV, the φ mesons are not suppressed. The ellipt...
متن کاملDirect Photon Production in Au+Au Collisions at RHIC-PHENIX Experiment
Direct photons have been measured with the PHENIX experiment in Au+Au collisions at √ sNN = 200 GeV. The direct photon result obtained with PHENIX-EMCal up to 18 GeV/c is consistent with the NLO pQCD calculation scaled by the nuclear overlap function. The measurement using internal conversion of photons into ee shows the enhancement of the yield comparing with NLO pQCD calculation.
متن کاملFluctuation and low transverse momentum correlation results from PHENIX
The PHENIX Experiment at the Relativistic Heavy Ion Collider has conducted a survey of fluctuations in charged hadron multiplicity in Au+Au and Cu+Cu collisions at √ sNN = 22, 62, and 200 GeV. A universal power law scaling for multiplicity fluctuations expressed as σ2/μ2 is observed as a function of Npart for all species studied that is independent of the transverse momentum range of the measur...
