QUARK-GLUON PLASMA and HEAVY ION COLLISIONS
In recent years many efforts have been devoted to the search for the Quark
Gluon Plasma, a new, deconfined phase of hadronic matter, through ultrarelativistic
heavy ion collisions. In 1986 the Alternate Gradient Synchrotron
in Brookhaven started accelerating nuclei, thus beginning the Era of high
energy nucleus-nucleus collisions. Since then, many experiments developed,
with increasing luminosity and energy of the ion beams: the Large Hadron
Collider, expected to be completed by 2007 at CERN will allow to study
Pb-Pb collisions at y/s ~ 5.5 TeV/nucleon....
