Direct Photons at RHIC
نویسنده
چکیده
sNN = 200GeV with the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) is given. Direct-photon yields for pT & 4GeV/c and photon-hadron azimuthal correlations were determined with the aid of an electromagnetic calorimeter. By detecting ee pairs from the internal conversion of virtual photons direct-photon yields were measured between 1 . pT . 4GeV/c. In Au+Au collisions thermal photons from a quark-gluon plasma (QGP) are expected to contribute significantly to the total direct-photon yield in this range.

متن کاملDirect Photons at LHC
The DGLAP improved color dipole approach provides a good description of data for inclusive direct photon spectra at the energies of RHIC and Tevatron. Within the same framework we predict the transverse momentum distribution of direct photons at the CERN LHC energies.
متن کاملDirect Photons from Relativistic Heavy-Ion Collisions
Direct photons have been proposed as a promising signature for the quark-gluon plasma (QGP) formation in relativistic heavy-ion collisions. Recently WA98 presented the first data on direct photons in Pb+Pb-collisions at SPS. At the same time RHIC started with its experimental program. The discovery of the QGP in these experiments relies on a comparison of data with theoretical predictions for Q...
متن کاملDirect-Photon Production in Au+Au Collisions at RHIC
Results from the PHENIX experiment on direct-photon production in Au+Au collisions at √ sNN = 200 GeV for transverse momenta 1 . pT . 13 GeV/c are presented. Direct-photon yields at high pT scale as expected for particle production in hard processes. This supports jetquenching models which attribute the suppression of high-pT hadrons to the energy loss of fast partons in the quark-gluon plasma....
متن کاملDileptons And Photons At RHIC Energies
Comparing dilepton data from Au+Au to p+p collisions at RHIC energies PHENIX revealed two striking features: (i) a large excess of the dilepton yield at low mass and low pT in central Au+Au and (ii) a significant enhancement of direct real photon radiation. Both features can be interpreted as thermal radiation from the hot quark matter produced at RHIC. Unlike at lower beam energies, at RHIC th...
