Measurements of dilepton continuum at the PHENIX experiment at RHIC
PHENIX has measured the dielectron continuum in √ sNN=200 GeV Au+Au and p+p collisions. In minimum bias Au+Au collisions the dielectron yield in the mass range between 150 and 750 MeV/c2 is enhanced by a factor of 3.4±0.2(stat.)±1.3(syst.)±0.7(model) compared to the expectation from our model of hadron decays that well reproduces the mass spectrum in p+p collisions. The integrated yield increas...
متن کاملPhotons at PHENIX
Direct photons are a powerful probe to study the properties of the unique matter created in ultrarelativistic heavy-ion collisions. They carry information on the various stages of a heavy-ion collision. At different transverse momenta (pT), different production processes dominate the direct photon yield in heavy-ion collisions. Photons at high pT can be used to study initial hard scattering pro...
متن کاملPHENIX Experiment at RHIC
The primary goal of the PHENIX collaboration is the detection and characterization of the quark-gluon plasma. We will outline the capabilities of the PHENIX experiment for measuring leptonic decays of the J/ and other quarkonium states.
متن کاملGlobal Observables at PHENIX
We present PHENIX recent results on charged particle and transverse energy densities measured at mid-rapidity in Au-Au collisions at √ s NN =130 GeV and 200 GeV over broad range of centralities. The mean transverse energy per charged particle is derived. The first PHENIX measurements at √ s NN =19.6 GeV are also presented. A comparison with calculations from various theoretical models is perfor...
متن کاملResults from PHENIX at RHIC
In nucleus-nucleus collisions at large c.m. energy or baryon density, a phase transition is expected from a state of nucleons containing confined quarks and gluons to a state of “deconfined” (from their individual nucleons) quarks and gluons, in chemical and thermal equilibrium, covering a volume that is many units of the confining length scale. This state of nuclear matter was originally given...
