High-p T Direct-photon Results from Phenix * Klaus Reygers for the Phenix Collaboration
Direct-photon measurements in p+p and Au+Au collisions at √ s NN = 200 GeV from the PHENIX experiment are presented. The p+p results are found to be in good agreement with next-to-leading-order (NLO) pertur-bative QCD calculations. Direct-photon yields in Au+Au collisions scale with the number of inelastic nucleon-nucleon collisions and don't exhibit the strong suppression observed for charged ...
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 کاملQuarkonium Production in PHENIX
Quarkonia provide a sensitive probe of the properties of the hot dense medium created in high energy heavy ion collisions. Hard scattering processes result in the production of heavy quark pairs that interact with the collision medium during hadronization. These in medium interactions convey information about the fundamental properties of the medium itself and can be used to examine the modific...
متن کاملMeasurements 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...
