Objective The study of high density nuclear matter,where new states are predicted by QCD, is the new frontier on the physics of the strong interaction. The experimental program of ultrarelativistic heavy-ion collisions aims to form and study these new phases. One of the main tools to characterize the created medium is the detection of particles produced with high transverse momentum: these particles are usually produced in form of 'jets', and the medium-modification of these jets carries essential information about t he medium. One of the main goals of the project is to provide the theoretical tools to study the medium-modification of the internal structure of a jet. On the other hand, high-density ('cold') states are also possible in the initial wave function of the c olliding particles: at high energies, the density of particles increases so much that a phenomenon of saturation appears. These effects are described by non-linear evolution equations computed in QCD and the observable consequences give information about t he dynamics under these extreme conditions. These are very rapidly growing topics in QCD phenomenology. In two years from now, the Large Hadron Collider (LHC) will study unexplored regions of this physics with unprecedented precision. The aim of the presen t project is to balance this enormous experimental effort of the European Particle Physics community with according theoretical developments.
