At high temperatures and densities the nuclear matter undergoes a phase transition to a new state of matter called quark gluon plasma (QGP). This new state of matter which existed in the universe after a few microsecond of the big bang can…

The energy densities achieved during central collisions of large nuclei at the AGS may be high enough to allow the formation of quark--gluon plasma. We propose that most collisions at AGS energies produce superheated hadronic matter, but in…
