The search of the Quark-Gluon Plasma (QGP) is the goal of the experimental heavy-ion program1. Existing data are limited to relatively light ions, and energies in the range E lab = 10 - 200 AGeV, and most of them can be described by models2, 3, 4, 5, 6 based on the production of colour strings, which decay independently into the observed hadrons. However, some new phenomena have been discovered, indicating that new theoretical suggestions are required. Particularly, the strangeness enhancement observed by several experiments7, 8 is not easy to explain by such models. The introduction of additional mechanisms, like colour ropes3 or string fusion9, is necessary. It is planned to study the heaviest nucleus collisions, when massive ion beams are available up to collider energies: E cm = 100 AGeV at Brookhaven-RHIC and E cm = 3000 AGeV at CERN-LHC. A change in the hadron production mechanism is expected: at lower energies, hadrons are produced essentially in soft collisions with small transferred momenta; at collider energies, the so-called semi-hard processes10 will dominate. The momenta transferred in such collisions are large enough to use Perturbative Quantum Chromodynamics (PQCD) calculations.
