Current Status of Quark Gluon Plasma Signals
Compelling evidence for the creation of a new form of matter has been claimed to be found in Pb+Pb collisions at SPS. We discuss the uniqueness of often proposed experimental signatures for quark matter formation in relativistic heavy ion collisions. It is demonstrated that so far none of the proposed signals like J/ψ meson production/suppression, strangeness enhancement, dileptons, and directe...
متن کاملCoupled Quark - Gluon Plasma : the Status Report
RHIC data have shown robust collective flows, strong jet and charm quenching, and charm flow. Recently " conical flows " from damped jets were seen. Non-Abelian classical strongly coupled plasmas were introduced and studied via molecular dynamics, with first results for its transport (diffusion and viscosity) reported. Quantum-mechanical studies reveal the survival for T > Tc of the lowest bina...
متن کاملSignals of the quark-gluon plasma in nucleus-nucleus collisions
The main motivation for studying nucleus-nucleus collisions at high energy is to learn the properties of the densest and hottest forms of matter that one can produce in the laboratory. One hopes in particular to reach the conditions under which hadronic matter is expected to turn into the quark-gluon plasma, a new phase of matter whose degrees of freedom are the hadron constituents, the quarks ...
متن کاملOn Signals of Quark - Gluon Plasma Freeze - Out
The timescales of rehadronization are considered for a baryon-free QGP at RHIC and LHC energies. The non-equilibrium nucleation scenario leads to the development of mechanical instability of the supercooled QGP phase which then may be suddenly converted in a timelike deflagration from the super-cooled state to a (super)heated hadronic matter. In a model simulation such a sudden process was inde...
متن کاملPossible Striking Signals for a Quark-Gluon Plasma at RHIC
We believe that one can have serious reservations as to whether heavy ion collisions (e.g. 100 GeV/n Au + 100 GeV/n Au) can lead to Thermal and Chemical equilibrium over large regions (particularly if it is assumed this happens whenever QGP is produced at RHIC-that is if it is produced). It is at present not clear that the collision dynamics and times available will lead to this. An alternate s...
