Gluon decay as a mechanism for strangeness production in a quark-gluon plasma.
A calculation of thermal gluon decay shows that this process contributes significantly to strangeness production in a quark-gluon plasma. Our analysis does not support recent claims that this is the dominant process. In our calculations we take into account the resummed form of the transverse and longitudinal parts of the gluon propagator following the Braaten-Pisarski method. Our results are s...
متن کاملPhoton production by a quark-gluon plasma
Photon or dilepton production by a hot plasma is expected to reflect rather cleanly the state of the system. Indeed, in the collision of two heavy nuclei, the typical size of the system is much smaller than the mean free path of particles that feel only the electromagnetic interactions, which enables photons and leptons to escape freely. However, it has been realized recently that those rates a...
متن کاملPhoton production from a quark-gluon plasma.
In-medium interactions of a particle in a hot plasma are considered in the framework of thermal field theory. The formalism to calculate gauge invariant rates for photon and dilepton production from the medium is given. In the application to a QED plasma, astrophysical consequences are pointed out. The photon production rate from strongly interacting quarks in the quark–gluon plasma, which migh...
متن کاملJ/psi production in quark-gluon plasma.
We study J/psi production at RHIC and LHC energies with both initial production at energies reached and the BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC) with regeneration. We solve the coupled set of transport equations for the J/psi distribution in phase space and the hydrodynamic equation for evolution of quark-gluon plasma. At RHIC, continuous regeneration ...
متن کاملStrangeness and Charm Signatures of the Quark-Gluon Plasma
Strangeness, charmonium and open charm yields in relativistic nucleus-nucleus collisions are considered within statistical model approach as potential signals of the quark-gluon plasma.
