Direct 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 کامل0 Photons from Ultra - Relativistic Heavy Ion Collisions
It is believed that a novel state of matter Quark Gluon Plasma (QGP) will be transiently produced if normal hadronic matter is subjected to sufficiently high temperature and/or density. We have investigated the possibility of QGP formation in the ultra-relativistic collisions of heavy ions through the electromagnetic probes photons and dileptons. The formulation of the real and virtual photon p...
متن کاملDirect Photons in Heavy-Ion Collisions
A brief overview of direct-photon measurements in ultra-relativistic nucleus-nucleus collisions is given. The results for Pb+Pb collisions at √ sNN = 17.3 GeV and for Au+Au collisions at √ sNN = 200 GeV are compared to estimates of the direct-photon yield from hard scattering. Both results leave room for a significant thermal photon component. A description purely based on hard scattering proce...
متن کاملPhotons from heavy-ion collisions at Fermi velocity.
The production of photons from heavy-ion collisions at intermediate energies is studied in the model based on the Boltzmann-Uehling-Uhlenbeck equation. Taking into account photon production from nucleon-nucleon collisions, the theoretical results are in reasonable agreement with the experimental data at 40 MeV/nucleon, but cross sections are smaller by about a factor of 5, compared to experimen...
